RAKE MINING AND HOW IT WORKS
The BetTronLive platform uses two currencies — TRX and RAKE. Both tokens have the TRC-20 format and the RAKE token is a registered name. To further drive the value of the RAKE token, only 100,000,000 tokens will be minted, and this number will never be increased.
RAKE tokens can be mined by playing certain games on the BetTronLive platform and by watching video ads before the live dealer games begin.
This is my handout for paranoid people who want a way to store bitcoin safely. It requires a little work, but this is the method I use because it should be resistant to risks associated with:
Bad random number generators
Malicious or flawed software
If you want a method that is less secure but easier, skip to the bottom of this post. The Secure Method
Download bitaddress.org. (Try going to the website and pressing "ctrl+s")
Put the bitaddress.org file on a computer with an operating system that has not interacted with the internet much or at all. The computer should not be hooked up to the internet when you do this. You could put the bitaddress file on a USB stick, and then turn off your computer, unplug the internet, and boot it up using a boot-from-CD copy of linux (Ubuntu or Mint for example). This prevents any mal-ware you may have accumulated from running and capturing your keystrokes. I use an old android smart phone that I have done a factory reset on. It has no sim-card and does not have the password to my home wifi. Also the phone wifi is turned off. If you are using a fresh operating system, and do not have a connection to the internet, then your private key will probably not escape the computer.
Roll a die 62 times and write down the sequence of numbers. This gives you 2160 possible outcomes, which is the maximum that Bitcoin supports.
Run bitaddress.org from your offline computer. Input the sequence of numbers from the die rolls into the "Brain Wallet" tab. By providing your own source of randomness, you do not have to worry that the random number generator used by your computer is too weak. I'm looking at you, NSA ಠ_ಠ
Brain Wallet tab creates a private key and address.
Write down the address and private key by hand or print them on a dumb printer. (Dumb printer means not the one at your office with the hard drive. Maybe not the 4 in 1 printer that scans and faxes and makes waffles.) If you hand copy them you may want to hand copy more than one format. (WIF and HEX). If you are crazy and are storing your life savings in Bitcoin, and you hand copy the private key, do a double-check by typing the private key back into the tool on the "Wallet Details" tab and confirm that it recreates the same public address.
Load your paper wallet by sending your bitcoin to the public address. You can do this as many times as you like.
You can view the current balance of your paper wallet by typing the public address into the search box at blockchain.info
If you are using an old cell phone or tablet do a factory reset when you are finished so that the memory of the private keys is destroyed. If you are using a computer with a boot-from-CD copy of linux, I think you can just power down the computer and the private keys will be gone. (Maybe someone can confirm for me that the private keys would not be able to be cached by bitaddress?)
To spend your paper wallet, you will need to either create an offline transaction, or import the private key into a hot wallet. Creating an offline transaction is dangerous if you don't know what you are doing. Importing to a client side wallet like Bitcoin-Qt, Electrum, MultiBit or Armory is a good idea. You can also import to an online wallet such as Blockchain.info or Coinbase.
Trusting bitaddress.org The only thing you need bitaddress.org to do is to honestly convert the brainwallet passphrase into the corresponding private key and address. You can verify that it is doing this honestly by running several test passphrases through the copy of bitaddress that you plan on using, and several other brainwallet generators. For example, you could use the online version of bitaddress, and brainwallet and safepaperwallet and bitcoinpaperwallet. If you are fancy with the linux command line, you can also try "echo -n my_die_rolls | sha256sum". The linux operating system should reply with the same private key that bitaddress makes. This protects you from a malicious paper wallet generator. Trusting your copy of bitaddress.org Bitaddress publishes the sha1 hash of the bitaddress.org website at this location: https://www.bitaddress.org/pgpsignedmsg.txt The message is signed by the creator, pointbiz. I found his PGP fingerprint here: https://github.com/pointbiz/bitaddress.org/issues/18 "527B 5C82 B1F6 B2DB 72A0 ECBF 8749 7B91 6397 4F5A" With this fingerprint, you can authenticate the signed message, which gives you the hash of the current bitaddress.org file. Then you can hash your copy of the file and authenticate the file. I do not have a way to authenticate the fingerprint itself, sorry. According to the website I linked to, git has cryptographic traceability that would enable a person to do some research and authenticate the fingerprint. If you want to go that far, knock yourself out. I think that the techniques described in this document do not really rely on bitaddress being un-corrupt. Anyway, how do we know pointbiz is a good guy? ;-) There are a lot of skilled eyes watching bitaddress.org and the signed sha1 hash. To gain the most benefit from all of those eyes, it's probably worthwhile to check your copy by hashing it and comparing to the published hash. "But we aren't supposed to use brainwallets" You are not supposed to use brainwallets that have predictable passphrases. People think they are pretty clever about how they pick their passphrases, but a lot of bitcoins have been stolen because people tend to come up with similar ideas. If you let dice generate the passphrase, then it is totally random, and you just need to make sure to roll enough times. How to avoid spending your life rolling dice When I first started doing this, I rolled a die 62 times for each private key. This is not necessary. You can simply roll the die 62 times and keep the sequence of 62 numbers as a "seed". The first paper address you create would use "my die rolls-1" as the passphrase, the second would be "my die rolls-2" and so on. This is safe because SHA256 prevents any computable relationship between the resulting private key family. Of course this has a certain bad security scenario -- if anyone obtains the seed they can reconstruct all of your paper wallets. So this is not for everyone! On the other hand, it also means that if you happen to lose one of your paper wallets, you could reconstruct it so long as you still had the seed. One way to reduce this risk is to add an easy to remember password like this: "my die rolls-password-1". If you prefer, you can use a technique called diceware to convert your die rolls to words that still contain the same quantity of entropy, but which could be easier to work with. I don't use diceware because it's another piece of software that I have to trust, and I'm just copy/pasting my high entropy seed, so I don't care about how ugly it is. Why not input the dice as a Base 6 private key on the Wallet Details tab? Two reasons. First of all, this option requires that you roll the die 99 times, but you do not get meaningful additional protection by rolling more than 62 times. Why roll more times if you don't have to? Second, I use the "high entropy seed" method to generate multiple private keys from the same die rolls. Using the Base 6 option would require rolling 99 times for every private key. I'm a big nerd with exotic dice. How many times to roll? Put this formula in Excel to get the number of times to roll: "=160*LOG(2,f)" where f = number of faces on the die. For example, you would roll a d16 40 times. By the way, somewhat unbelievably casino dice are more fair than ordinary dice The "Change address" problem: You should understand change addresses because some people have accidentally lost money by not understanding it. Imagine your paper wallet is a 10 dollar bill. You use it to buy a candy bar. To do this you give the cashier the entire 10 dollar bill. They keep 1 dollar and give you 9 dollars back as change. With Bitcoin, you have to explicitly say that you want 9 dollars back, and you have to provide an address where it should go to. If you just hand over the 10 dollar bill, and don't say you want 9 dollars back, then the miner who processes the transaction gives 1 dollar to the store and keeps the remainder themselves. Wallet software like Bitcoin-Qt handles this automatically for you. They automatically make "change addresses" and they automatically construct transactions that make the change go to the change address. There are three ways I know of that the change problem can bite you:
You generate a raw transaction by hand, and screw up. If you are generating a transaction "by hand" with a raw transaction editor, you need to be extra careful that your outputs add up to the same number as your inputs. Otherwise, the very lucky miner who puts your transaction in a block will keep the difference.
You import a paper wallet into a wallet software and spend part of it, and then think that the change is in the paper wallet. The change is not in the paper wallet. It is in a change address that the wallet software generated. That means that if you lose your wallet.dat file you will lose all the change. The paper wallet is empty.
You import a paper wallet into a wallet software and spend part of it, and then think that the change is in the change address that the wallet software generated. If the transaction did not need to consume all of the "outputs" used to fund the paper wallet, then there could be some unspent outputs still located at the address of the paper wallet. If you destroyed the paper wallet, and destroyed the copy of the private key imported to the wallet software, then you could not access this money. (E.g. if you restored the software wallet from its seed, thinking all of the money was moved to the wallet-generated change addresses.)
For more on this, see here The hot paper wallet problem Your bitcoin in your paper wallet are secure, so long as the piece of paper is secure, until you go to spend it. When you spend it, you put the private key onto a computer that is connected to the internet. At this point you must regard your paper wallet address as hot because the computer you used may have been compromised. It now provides much less protection against theft of your coins. If you need the level of protection that a cold paper wallet provides, you need to create a new one and send your coins to it. Destroying your paper wallet address Do not destroy the only copy of a private key without verifying that there is no money at that address. Your client may have sent change to your paper wallet address without you realizing it. Your client may have not consumed all of the unspent outputs available at the paper wallet address. You can go to blockchain.info and type the public address into the search window to see the current balance. I don't bother destroying my used/empty paper wallet addresses. I just file them away. Encrypting your private key BIP 0038 describes a standardized way to encrypt your paper wallet private key. A normal paper wallet is vulnerable because if anyone sees the private key they can take the coins. The BIP38 protocol is even resistant to brute force attacks because it uses a memory intensive encryption algorithm called scrypt. If you want to encrypt your wallets using BIP38, I recommend that you use bitcoinpaperwallet because they will let you type in your own private key and will encrypt it for you. As with bitaddress, for high security you should only use a local copy of this website on a computer that will never get connected to the internet. Splitting your private key Another option for protecting the private key is to convert it into multiple fragments that must be brought together. This method allows you to store pieces of your key with separate people in separate locations. It can be set up so that you can reconstitute the private key when you have any 2 out of the 3 fragments. This technique is called Shamir's Secret Sharing. I have not tried this technique, but you may find it valuable. You could try using this website http://passguardian.com/ which will help you split up a key. As before, you should do this on an offline computer. Keep in mind if you use this service that you are trusting it to work properly. It would be good to find other independently created tools that could be used to validate the operation of passguardian. Personally, I would be nervous destroying the only copy of a private key and relying entirely on the fragments generated by the website. Looks like Bitaddress has an implementation of Shamir's Secret Sharing now under the "Split Wallet" tab. However it would appear that you cannot provide your own key for this, so you would have to trust bitaddress. Durable Media Pay attention to the media you use to record your paper wallet. Some kinds of ink fade, some kinds of paper disintegrate. Moisture and heat are your enemies. In addition to keeping copies of my paper wallet addresses I did the following:
Order a set of numeric metal stamps. ($10)
Buy a square galvanized steel outlet cover from the hardware store ($1)
Buy a sledgehammer from the hardware store
Write the die rolls on the steel plate using a sharpie
Use the hammer to stamp the metal. Do all the 1's, then all the 2's etc. Please use eye protection, as metal stamp may emit sparks or fly unexpectedly across the garage. :-)
Use nail polish remover to erase the sharpie
Electrum If you trust electrum you might try running it on an offline computer, and having it generate a series of private keys from a seed. I don't have experience with this software, but it sounds like there are some slick possibilities there that could save you time if you are working with a lot of addresses. Message to the downvoters I would appreciate it if you would comment, so that I can learn from your opinion. Thanks! The Easy Method This method is probably suitable for small quantities of bitcoin. I would not trust it for life-altering sums of money.

Hey all! GoodShibe here! I'm technically still on vacation, but in light of the news out of New York... I feel the need to comment. If you're not aware of what's going on, the New York State Department of Financial Services is proposing a new regulatory framework for how all Cryptocurrencies work for the residents of New York State. However, the way that it's worded, the way that it's been presented, it's incredibly vague in some areas while being incredibly strict in others. They're designed to take 'untraceable digital cash' and, at pretty much every point along the chain, put someone's face and name to who had what and when. This, of course, weakens Cryptos immediately in compared to, well, cold, hard cash -- which is largely untraceable. This bill, as it has been designed, seems to try and have a massive chilling effect on cryptocurrencies in general. You can use cryptos, sure, but by the time they're done with them... why would you want to? You can read the proposed Regulations here. AmericanBitcoin has put together a TL;DR of the proposed reglations goldcakes has put together a TL;DR of some of the ramifications If you'd like to see a quick breakdown of exactly what's wrong with the proposal, I highly recommend you read this comment by MrMadden over in /Bitcoin, which is utterly fantastic. dalovindj also has a great post on how this would effect our fellow Shibes. Here's the thing: We always knew that this was going to be a problem. The idea that somehow the old, established system would just roll over and let the next generation step up to the plate without a fight is laughable. And now we've seen the first volley. The warning shot off the port bow, so to speak. The regulations that are coming out are, well, typical government overreach designed, specifically, to elicit the reaction that they are. They're big and scary and over-reaching. But they're also designed so that, IF there's a public outcry, at a large enough scale, they can 'pull back' the more offensive over-steps and still come out of this with the regulation that they REALLY want. If nobody stands up to complain or fight back about it... then bonus for them. The city of New York then gets global over-reach on a massive scale all under the guise of 'protecting it's citizens'. Incidentally, if you hadn't noticed, Canada set the wheels in motion recently, with the first 'Bitcoin Law' which caused quite an uproar (remember when DogeDice closed down rather than meet the Canadian Government's new regulations?). Here's the thing - and it's a truth that's as immutable as time itself: Governments are going to Govern. They will always move to exact as much power as we let them have over any new or emerging technology, especially where money is involved. So... what can we do about it? For those who don't live in the US, the best thing you can do is learn about this regulation - because, whether you like it or not, the Government of the State of New York is making it your business. Because anyone who does business with residents of the State of New York will have to submit to these regulations as well. Meaning that if you do business with a business that does business with the state of New York, you will be subject to those same overreaches. The long and short of the problem is this: You have 45 days, starting on July 23rd, once the Regulations are formally published, to make a case to the people of New York that, whether they realize it or not, this bill is trampling their rights. Because, that's how you defeat this issue. We need to get NEW YORKERS to care about this issue. If you're not in New York, your job is now to find a way to help make New Yorkers care about this issue. I don't care which banner your coin flies - Bitcoin, Litecoin, Dogecoin, Reddcoin, Potcoin... this is effects us all and it's only just getting started. How will this bill effect them? It might not, directly, lots of people aren't using cryptos yet. But it's the first step in something larger. If this goes through unchallenged, then I foresee a whole new legal arms race to 'protect' ones citizens from, well, anything they like. Because this is '... but think of the children!' for a whole new era. This is classic government overreach. If you're living in New York, you need to get in touch with your local representatives and let them know, unequivocally, that this is a voting issue for you. That you will be watching to find out if they support this bill, and that if they do, you will be voting for the other guy. The best way to deal with this problem is not to 'get angry'. It's to 'get angry and get to work'. Forget waiting for the Lobbyists and their big money to tell you how it's going to be. If you want cryptos to survive - and this legislation, as stated, would make illegal having a QT wallet/node running on your computer - then -- every crypto-user on this planet -- is now a Lobbyist. And, for my fellow Shibes, if there's one thing that /Dogecoin has proven good at, it's in getting the word out there. We're smart, we're media savvy - we know how to get attention! So, let's get organized. Bring everyone on board - every coin, every crypto-user in every corner of the world. Let's get active. Because we've still got time to fight this. Together! It's 8:50AM EST and we've found 87.62% of our initial 100 Billion DOGEs -- only 12.38% remains until our period of Hyper-inflation ends! Our Global Hashrate is up from ~44 to ~46 Gigahashes per second and our Difficulty is up from ~641 to ~815. As always, I appreciate your support! GoodShibe EDIT: I've created this brainstorming thread to try and help get ideas moving. Come join me! EDIT 2: I've also started this post to ask for the community's permission/support to reach out to /bitcoin and other communities to try and organize a crypto-wide response to these regulations.
Hi everyone, I know very few people will see this and that's okay. I decided after a week of severe depression, anxiety, self-loathing, and general fucked up thoughts that I needed to talk about what I did. On the scope of a confession, it isn't much to some people, but to me it is a huge and daunting fuck up that I'll be paying out the nose for. The reality is I might even be homeless due to this. I used a throwaway for this because a few people I know have my primary acct and I can't bear the shame of them knowing yet. To get to it, I made a huge mistake and lost all my money. ALL OF IT. If it isn't obvious already, I don't have a lot of money. I am not a all that familiar with bitcoin and only recently began taking part in the community. /Bitcoin has been my bible and go to source nearly every day for the last 6 months. But again, I don't have much money and I decided that I have a this tremendously good feeling about where bitcoin is going so I warily invested in a couple coins around January 2nd at about 809 a coin from coinbase. I was terrified of losing what I put in. Then the next day, the price jumped about $30! I was ecstatic! I was amazed! I couldn't believe that my investment had begun working for me after only a day! It was a great feeling. At the same time of all this, I had just finsihed up a huge ordeal with Bank of America over fradulent charges on my debit card that sent my account into the negative and had intitially accured almost $1000 in overdraft and other fees. It took months to get all my money back and in the end still lost out on about $200 dollars. Needless to say, I was more wary of my bank than bitcoin at this point and bitcoin was GIVING me money instead of giving it away. So I did the only logical thing I could think of at the time and put the rest of my savings into BTC. And guess what? It went up again! I was so happy with my decision that I started reading more and more about BTC. Then the fluctuations in the BTC market started happening. I started to get nervous because the only cash I had was losing value and fast. I knew that it had a habit of fluctuating like that but I never had any money invested before. The anxiety was real for me every day I'd hop on /Bitcoin and see the news about mtgox ( then after that the silkroad 2 hack.) So, about a week ago when coinbase's price was plummeting still due to gox's problems and bad press and so on I started getting nervous. More nervous than I had been before. My "investment" had lost almost 200 a coin and I was sick to my stomach watching and waiting for the price to come back up like it "always" does. I was posting around a few forums and asking questions about what I should do? What could I do in the mean time? Should I pull out and take my losses? I got to talking to this guy on one of the forums who seemed to know what he was talking about. He mentioned the dice site satoshi bones and how he was in the same spot as me, made one bet and came out 10BTC richer. Even sent the tx ids. It was awesome to see and was even more awesome to imagine. He went as far as to send me .05 btc (holy shit!) and said "Make a few bets and watch, some of the odds are great." So I did that. I sent a few bets of .001btc and made nearly .5 btc in 5 minutes. I was hooked. I was going to make my money back. I was going to make a few bets and get out with what I put in, no more. So I proceeded to make bigger bets. I was making money. I was getting good at watching and "considering the odds." It wasn't really the case, I was just geting lucky here and there. I had no idea what the fuck I was doing. Then the transaction malleability thing happened. Or, rather, it was probably happening the whole time. I don't know. I don't know what it did to my MultiBit account, but it was sending my coins and not updating my balance. I was losing more than I knew because the double spends ended up looking like I had more in my overall account than I did. At one point, it appeared that I had TRIPLED my initial BTC investment over all and I was nearly crying with joy. Then I couldn't access my funds. It said I had a "Balance" of 30btc, but "Spendable" was .05. I knew that it took a little while for the transactions to get through the system and clear but minutes turned into hours and hours into days. When the whole story about the transaction malleability broke into full swing I started tracing my tx IDs back. I was a nervous wreck at that point. I had so many double spends and unconfirmed transactions that there was no way to actually find out how much I truly had left. When I looked through multibit's logs, it had mulitples of the "wins" that I knew I had but numerous tx Ids. I couldn't keep track of it all. Attempting to "reset" the blockchain on Multibit would only cause it to crash (probably because I had sent and received sooooo many unconfirmed transactions back and forth between that game.) I decided to grab my private keys and attempt to use Bitcoin-QT to sort it all out to no avail. It too said I had a balance around 30 BTC unconfirmed (a mind blowing amount of money for me!!!!!) I relaxed and decided I would just have to wait it out to get my money and I'd hold off on grocery shopping until the weekend (today.) Even if I had half of that after it all cleared up, I'd have made a HUGE profit. About two days ago everything calmed down and my balance began fluctuating like mad on both the Multibit client and Bitcoin-qt. It went UP at one point to 40 BTC even! Then transactions started to disappear. Mostly, the transactions that disappeared were the "wins." I assume this is because all of the unconfirmed txs or double spends started being pushed out of the system? I have no idea. I'll take a second to mention that I've never had an interest in gambling whatsoever. I've been to vegas, played a few slots, sat in for some poker and blackjack, would lose and just walk away. However, the last couple days I was consumed by the dice game. I thought I was making incredible money, hand over fist. Yesterday, my balance completely cleared up. I'm broke. I have nothing left. I pissed away even my winnings (maybe 3btc) I had before the transaction malleability started fucking things up. I cried for the first time in 10 years yesterday. Today, I cried again. Over the last week I fell into a depression and was overcome by this urge to just stop existing. Not really suicide at first, but, more of a "I want to close my eyes and let it all blow over." Then, when that didn't happen, I did start considering suicide. I have no money left. I don't know what the fuck I'm going to do for rent, for food, for gas, for my fucking books next quarter. I moved to california on my own about 3 years ago and have zero family in the area. I don't have family to lean on finacially whatsoever (I come from a seriously bad luck/misfortune/poor family.) Monday I'll be heading to my university to find out what I can do and if I qualify for any loans. Or something. I don't know. But right now, I need to tell people and persevere and try to make it out of this. But, my point of posting here isn't a pity party or to draw out "sorry for the bad luck" responses. I did this to myself and this pales in comparison to the bad luck others have had. I want people to use my sincere and obvious FUCK UP as a lesson. I got caught up thinking I was making money. I wasn't fully aware of what was happening during the transaction malleability shit and made decisions without fully comprehending the situation (and it is NOT the fault of Mulitbit or the dice game even if I wanted something to blame.) Most of all, I was GAMBLING my money away. It was greed and poor decisions. But mostly greed. So, I fucked up. I don't want YOU to fuck up like I did. Please look at the story and realize that it can happen to anyone without fully thinking through your decisions and having a grasp on the situation. And SERIOUSLY consider when you're putting too much money at stake when gambling. You could regret it and be in a shitty spot like myself. Thanks for reading. TL;DR Holy shit I wrote a novel. Sorry. In short, I inadvertently gambled away my only $7000 during the transaction malleability crisis and it is no one's fault but myself. I am now broke and terrified and I don't want YOU to suffer like I did. Do not gamble and do research before you do anything with your money especially if it is all you have. EDIT: Though my intial reason for posting was NOT to focus on why my balance said one thing and the actual balance was another, here is what the balance looks like on my Multibit client right now. However if you look at the blockchain, that's clearly not the case and hasn't been for days and days. These are the addresses I used off and on. Not all of them but those were the most active I think. 17cHzgxRLumqfu6UAddUrJmTujd7goHLrx 1BAKHq37qj1xekitr7adXapLqFrVtAhm8A 1KLug6D1mXoyS12BZipyQ8WHAdNzDmQxMp. Also, when I opened the Client today it seemed to send or revieve "stuck" transactions? I don't know what to tell you all beyond that.
Confession on how I got away with $1500 in Bitcoins for free
So first of all, yes, I'm using a throw-away account and Tor (Apparently you have to use https://pay.reddit.com/ in order to login through Tor. The regular http://www.reddit.com/ let me register but wouldn't let me login. Just FYI for anyone having the same problem.) Call me a coward if you like. Anyway, this happened a few months back. I was trying the wallet encryption feature for the first time on Bitcoin-QT. I got it setup but wanted to verify I could send and receive coins (and also that it would prompt for a password each time.) To do so, I figured I'd have a little fun and try out PrimeDice. I'm not much of a gambler (I never bet more than $20 at a time and I usually end up losing) and this was really only a test so I sent, I don't remember, about $1 or $2 worth of bitcoins over. Bitcoin-QT prompted me for my password as it should have. I rolled the dice a couple times and actually came out ahead by a small amount (won 50 cents or something.) Then I hit cashout. Transaction comes in OK for the correct amount but then, what's this? Another transaction? Then another? And another? And another? I'm thinking oh great I must have glitched my wallet. But then they start confirming. At that point I realized I just hit the Bitcoin equivalent of winning the jackpot. Somehow PrimeDice messed up bad and sent my small transaction to me over 100 times (actually math tells me it would have been over 700 times, I don't remember.) And it wasn't just a double spend. Every. Single. Transaction. was valid and confirmed through the blockchain. It was popping up "received new bitcoins" on my screen about every 10-30 seconds for hours. I had already stayed up far too late watching the transactions come in and had to work very early in the morning so I forced myself to go to sleep after I had received about $500 worth, knowing the money was still flowing in. Woke up to the full amount and just though "Holy Shit. What are the chances? This is almost a month's worth of income for me for free." Anyway, I ended up cashing it all out to fiat so I have none of those bitcoins left. I have this mistake to thank for my new monitor and GPU I'm using to type this. I'm not proud of my actions but I'm curious: If you were in my situation, what would you do? It would be like if you went to the ATM (that you somehow knew not to have a security camera and with no one else standing around) to take out $20 and it just glitched and kept spitting out money. Then you look at your bank statement and you only get charged for the $20. Me personally, I would have no hesitation at all stealing from someone like Bank of America. I feel a bit worse about taking coins from a smaller player like PrimeDice. If it was an individual person, I probably would have given the money back. Does that make it right? No, but $1500 doesn't make all that much difference to them but it's a hell of a lot of money for me making only marginally better than minimum wage. Also, since it's a gambling service, I just took at as a large win. Happens all the time, right? And what business do they have using semi-anonymous currency with no method of collecting refunds if they can't design their systems properly? I just gave them a hard lesson (but not too hard, I doubt $1,500 would really hurt them, just give them a wake up call to fix it before it becomes $15,000. I also waited a couple months to post this so they had time to fix it. I see they've re-designed their site now and this happened prior to the re-design so good chance the bug is patched now.) These justifications are paper-thin, I know. Just giving you an idea of my mindset at the time. So, go ahead, flame me, down-vote me, call me a thief if you like but put yourself in my shoes and ask yourself what you would honestly do. Some of you would give it back, I'm sure. But most? I don't know.

But that doesn't mean you have to settle for a plate of food you feel shitty about putting in your body—just smarten up about meal planning, instead. For example, you can swap out pricey organic meat and dairy for more cost-effective protein-packed fare like lentils, black beans, and whole grains. And never overlook the value—and time savings—you can get with buying an organic frozen meal or premade ingredients, from time to time. As you'll see from the nine dinners here, cheap and organic can actually go hand in hand: All our meals ring in at less than $5 per serving. 1) Mango, Avocado, and Black Bean Salad with Lime Dressing "Organic meats are going to be expensive; a pound of organic ground beef is roughly $7 at the supermarket," says Libby Mills, RDN, a spokesperson for the Academy of Nutrition and Dietetics. "But a can of organic black beans is a mere $2. A bag of dried organic black beans? Even cheaper." Serves 6 2 ripe but firm avocados, pitted, peeled, and cubed3 Tbsp lime juice2 ripe but firm mangoes, pitted, peeled, and cubed1 jalapeño, stemmed, seeded, and finely chopped2 Tbsp chopped cilantro, plus more for garnish1 tsp freshly grated lime zest½ tsp sea salt¼ tsp freshly ground black pepper¼ tsp sugar3 Tbsp extra virgin olive oil1 can (15-oz) no-salt-added black beans, rinsed and drained 1. Gently toss avocado with 1 Tbsp of the lime juice in medium bowl. Add mango and jalapeño and gently toss to combine. Set aside.2. Whisk remaining 2 Tbsp lime juice, cilantro, lime zest, salt, pepper, and sugar in large bowl. Whisk in oil until thoroughly combined to make thick dressing. Add avocado mixture and black beans and toss gently. Spoon salad onto plates, garnish with cilantro and serve immediately. (Recipe via Whole Foods Market) 2) Whole Grain Tabbouleh Salad No one thinks about whole grains as a protein source, but—surprise, surprise!—they are, with 1 cup of quinoa, oats, and even whole wheat averaging about 6 g of protein (the same amount found in an egg). Even better, organic grains are super budget-friendly. Organic quinoa costs, on average, $0.75 per 1/4 cup serving. "Buy bulk or store-brand organic grains, and prevent overbuying for a recipe by bringing your own measuring cups to the store to measure bulk ingredients," suggests Mills. Serves 4Total Time: 35 minutes 1 c cooked quinoa, millet, or barley1¾ c vegetable broth1 lg ripe tomato, diced½ c finely chopped cucumber⅓ c chopped scallions⅓ c chopped fresh mint¼ c chopped fresh parsley and tender stems¼ c extra virgin olive oil3 Tbsp fresh lemon juice 1. Rinse quinoa in fine metal strainer until water runs clear. Transfer to medium saucepan. Add vegetable broth and bring to a boil. Reduce heat and simmer, covered, 30 minutes. Turn off heat and let stand 5 minutes. Fluff with fork. 2. Spread quinoa onto sheet pan to cool. (You can prepare quinoa a day in advance and keep chilled until ready to use.) Transfer cool quinoa to salad or mixing bowl.3. Add tomato, cucumber, scallions, mint, parsley, oil, lemon juice, and salt and pepper to taste. Stir well. Cover and chill before serving.Lentils are another plant-based protein and money-saving superstar. Organic large green lentils average about $2.49 per pound. "I love this recipe because it makes a light, yet substantial dinner in a pinch," says Mills. Makes 2 quarts 1 c green lentils3 Tbsp olive oil2 lg stalks celery, diced2 med large carrots, peeled and diced1 lg onion, diced2 cloves garlic, minced2 tsp salt½ tsp freshly ground black pepper1 bay leaf1 qt vegetable or chicken brothPinch red-pepper flakes 1. In large pot, bring 1 qt water to a boil. Add lentils and remove from heat. Let soak for 15 minutes. Drain water and set lentils aside in bowl.2. Return same pot to stove; add oil then celery, carrots, and onion. Sauté over medium heat until vegetables are tender and onion is translucent. Add garlic, salt, pepper, and bay leaf. Cook, stirring, 1 minute.3. Add lentils and vegetable broth. Cover and simmer over low heat, 1 hour. Ensure liquid covers lentils, adding more broth if needed. Discard bay leaf before serving.4. Serve with red-pepper flakes and a dollop of sour cream. For more summer flavor, add chard or spinach. Cut leaves into bite-size pieces, removing thick center veins. Add chard in the last 10 to 15 minutes of cooking time and the spinach in the last 5 minutes. 4) Vegan Zucchini-and-Cashew-Nut Stuffing"This recipe can be enjoyed as a main course casserole with a side of cooked asparagus and fresh garden salad," says Mills. "Or used as a stuffing to baked tomatoes, baby artichokes, or mushroom caps." Serves 8 to 12 3 c oats2 c peeled and shredded zucchini2 c cooked quinoa2 c diced tomatoes2 c diced onions2 c vegetable broth1 c coarsely ground raw cashew nuts1 c minced fresh parsley3 garlic cloves, minced2 tsp sea salt Mix all ingredients and pour into 13" x 9" pan lightly coated with cooking spray. Bake at 350°F for 45 to 50 minutes. (Recipe via Libby Mills) 5) Shake and Eat SaladsAll you need is a mason jar and a good grip to shake up this organic meal. Sub in 2 to 3 tablespoons of salsa for the Honey Lime Cumin dressing to cut down on prep time and switch up the flavor. Dressing1 Tbsp red wine vinegar2 tsp honey2 tsp fresh lime juicePinch cumin Salad⅓ c cooked black beans or quinoa⅓ c cooked corn kernels1 Roma tomato, diced1 c chopped romaine lettuce, washed and dried Add all ingredients to mason jar. Start with dressing ingredients, then beans, corn, and tomatoes. Add lettuce last. Chill until ready to shake and eat. 6) 365 Organic Vegetable Lasagna or Vegan Lasagna ($3.99 for 1 serving)Realistically, not everyone has time to make an elaborate, healthy meal come 8 PM. The good thing is that supermarkets like Whole Foods are stocking their freezer cases with affordable, pre-made organic dinners that are nothing like the sketchy TV dinners you ate as a kid. This lasagna is made with all organic ingredients and costs less than $4 per serving. All you need to do is heat and eat. 7) Engine 2 Plant-Strong Fiesta Blend and Wild Rice Blend ($3.99 for 3.5 servings)This brand's frozen whole-grain combos, like the Fiesta Blend and Wild Rice Blend, cost less than $1.25 per serving. Mix into salad, sautéed greens, or pair with a small piece of protein and you've got yourself a clean, well-balanced meal that's ready to eat in less than 10 minutes. 8) 365 Organic Quinoa with Vegetables ($3.99 for 2.5 servings)Quinoa does take a little while to cook, so no one will blame you for opting for a precooked batch every now and then. 365 Organic Quinoa with Vegetables is a mix of white and red quinoa, sweet potato, and zucchini. One serving rings up to about $1.50. Pair it with an organic turkey burger and dinner will still only set you back as much as one latte at Starbucks. 9) Amy's Black Bean Burrito ($2.99 for 1 serving)This quick and clean source of plant-based protein (8 g per serving) will replenish your body at the end of a rough day for less than $3. Heat it up, chow down, and bask in the glory of knowing that you could have paid for this meal with the loose change you have hanging out in the junk drawer. Source
Colored coin client preview #1 (based on Bitcoin Armory)
I think it's already good enough for people to play with it. (Although certainly it's not ready for anything serious.) For people who are not familiar with concept, colored coins is a technology which allows people to represent arbitrary tokens (e.g. issue private currencies, stocks, bonds, etc.) using small quantities of bitcoins. It is interesting because it would allow us to create decentralized and secure markets. (As decentralized and secure as Bitcoin itself, at least in theory.) See here. Notes about current release:
There is a GUI for issuing new coins. So all you need is like a small sum of Bitcoins, this software, and you can issue your coins and start selling them. (It is another question why people would want to buy them... Perhaps you will offer to buy them back later at higher price, thus creating bonds.)
p2p trade and auto-trade are not implemented yet, so it is only possible to trade OTC.
It is very lightly tested so please don't use it for anything serious.
It is a patched version of Armory, so it isn't lightweight at all: It requires running bitcoind or Bitcoin-Qt version 0.7.*, then it takes about 10 minutes to launch it, and in its final form it eats 1 GB of RAM. But it is totally worth it. (Yes, we are working on lightweight clients.)
(Note: if you're already using Armory, it is a good idea to hide you ~/.armory so it won't be seen by this experimental Armory mod. Or, perhaps, just don't run this experimental mod.) Before you run it, make sure that bitcoind or Bitcoin-Qt is running and fully sync'ed. Armory takes up to 10 minutes to start (this version is slower because it additionally scans for colored transactions) and requires ~ 1 GB of RAM. At start it will offer to create a wallet, do not enable encryption, otherwise issuing colored coins won't work. Send some bitcoins to this new wallet, 0.02 BTC is probably enough to issue some colored coins and to pay for tx fees. There is a drop down to choose color. Balance is displayed for a currently chosen color (i.e. if you chose TESTcc it will show how many TESTcc units this wallet owns), and when you send coins you send coins of that color. Initially 'uncolored' is selected, it means normal BTC. This drop down also has TESTcc ("test colored coins") and "All colors" (this mode is just for debugging, you cannot send coins in this mode). Here's what you can do now:
Ask somebody to send you TESTcc. (We want to make it automatic, Satoshi Dice style, but unfortunately that code isn't quite ready.)
Find and install other color definitions.
Issue your own colored coins and send them to somebody who wants them. (LOL.)
Let's start from option #3. There is 'Hallucinate' menu. (It is called 'hallucinate' because colors do not exist on blockchain level, it is a client-side convention.) Choose 'Issue colored coins'. Likely all you need to change is name, but you can tweak satoshi-per-unit and number of units if you want. When you click Issue it will create a new transaction (using your uncolored BTC) and will create a color definition. Optionally it will also upload your color definition to color definition registry. (This registry runs on my server, it might be down.) You should note ColorID, this is how other people can refer to these coins (name is ambiguous). You can now choose this new color in drop down and it will show your balance. (E.g. 1000 units.) Now you'll perhaps want to send these coins to somebody. That person would need to install your color definition first. If you send colored coins without warning they might be lost, i.e. mixed with uncolored ones. For same reason it makes no sense to send them to wallet which isn't color aware. For example, you can post on some forum:
I've issued LOLwut coins (ColorID: 36738fe78a443656535503efb585fee140a37d54), each unit represents a bond with face value of 0.1 BTC payable by me, Trololo, via buy back. I promise to buy back all bonds in a month.
Now people who are interested in this LOLwut coin issue will copy ColorID, paste it into Hallucinate > Download color definition dialog, and if this color definition is published it will be downloaded and installed. Armory restart is required to complete installation. After installation that person will be able to see these LOLwut coins. Note that if you do not trust my registration server, you can publish color definition yourself: go to ~/.armory/colordefs, find 36738fe78a443656535503efb585fee140a37d54.colordef and upload it to your web server. Then you can give people URL like http://example.com/36738fe78a443656535503efb585fee140a37d54.colordef and they can download it by URL. Or they can just obtain this file by any means and copy it to ~/.armory/colordefs directory. It is decentralized, nobody can prevent you from issuing colored coins. I think that's all. There is also Hallucinate > Manage color definitions dialog, but I hope it's easy to figure out how it works. We are working on improved version, particularly on p2p exchange feature. I've set up an IRC channel for people to talk about trying out colored coins: #colored-coins-otc on Freenode.
Raspberry Pi Node woes- moving blockchains copies between Windows and Linux
My Pi 2 was being slow to sync. So I plugged its USB drive into a Windows 8 laptop and ran bitcoin-qt for a few days until everything was synced. I tried to plug the USB drive back in the Raspberry Pi, but the bitcoin-qt won't recognize the data, even though I can see it browsing the RPI. I tried all sorts of -rescan and -detachdb commands on both units, but no dice. The Pi is resyncing the blockchain, but adding to the USB drive instead of replacing the files.
Any way I can force bitcoin-qt to rescan the drive or do anything to recognize the already existent blocks when running on the Pi? The Pi can browse what appears to be a complete blockchain through its file explorer.
If I can't save the old blocks, which files at least can I delete? The files are at 50 GB already and will push at least another 30 GB downloading the rest of the second blockchain. However, looking at the file structure it's not clear which blocks are new or no longer important.
Block size: the matter between purchasing power, and microtransactions in Bitcoin
Bitcoin is no good for handling microtransactions, due to all transactions are stored in mined blocks. However if the price is continue rising at the current rate, and Bitcoin is accepted by more businesses, then we could see there will be more and more microtransactions due the purchasing power per unit Bitcoin is increasing. Lots of microtransactions can be a problem. It becomes noticeable when guys on the bitcointalk with lots of microtransactions from SatoshiDICE or other faucet sites wants to send them into one address and to reduce transaction fees. They end up to pay more transaction fees than the sum of those dust values. I am not talking about the transaction fee. The fee may be required to store a transaction into a block in order to prevent DDOS attacks to the network, and i have no doubt of that. The matter is the block size. And I suppose the developers already notice the size issue when the block size is enlarged in bitcoin-qt 0.8. This is a good sign. I think the true value of Bitcoin can be higher, but there are still more works to be done to the protocol and to economic environment of Bitcoin. I hope everything about Bitcoin should be ready before it can be showed to the rest of people on the earth. (I am a non-English speaking user, and this is just my own opinions)
