Idea: r/Bitcoin creates a simple "How to Start a Local Bitcoin Club" wiki, to promote towns/neighborhoods using Bitcoin for regular buying and selling business between peers
Inspired by this post https://www.reddit.com/Bitcoin/comments/cp5y2s/10_out_of_22_btc_was_spent_by_bitcoin_subreddit/ I'd love to see us promote the original purpose of Bitcoin, which is a peer-to-peer way to trade money directly between individuals' wallets, rather than via exchanges or other middleman sites (like Bisq) or processing companies (like Bitpay). I know that I got into Bitcoin when some cool folks on Reddit were giving it away to anyone who asked, and that made me get a wallet and learn how to use it. It was just so much easier than trying to get into an exchange (which I eventually did do, because I wanted to get more). So, since it seems like one of the biggest challenges to Bitcoin adoption is not having anyone to trade with, and creating local Bitcoin clubs, to help people connect to one another, personally, so that they can offer and receive bitcoin for whatever kinds of exchanges they want to do, could be an extremely useful tool. Local businesses could sponsor or just join the clubs as well, so that folks in a community build up strong connections for using Bitcoin for normal business. Also, the more we exchange Bitcoin with people we are closer to (than central exchanges and the total strangers on them) the more we focus on making sure that exchanges are "fair" in the sense of not trying to only trade it away or spend when it's high, and just using it all the time, so that losses and gains are less pronounced, and folks are more comfortable using it all the time. Maybe we could put together a little "how to form a Bitcoin club" website/video/flyer for anyone to use and share.
I created a page cataloging backup and storage methods on the bitcoin wiki - looking for more info
https://en.bitcoin.it/wiki/Backup_and_Storage_Methods This page is intended to review existing methods to help people make informed choices (more help needed!). I'm wondering if anyone out there knows of other published methods on how to properly store and backup a bitcoin wallet. Ideally, these would be methods that are as well put together as glacierprotocol.org but any method that attempts to be complete (even if it isn't) would be helpful. Its also useful to document which protocols are not safe and why. So anything of the level of quality of anything currently on that page would be helpful. So does anyone know any methods that aren't already on the list?
Hi, I have been using CoinBase but recently ran into some issues with their service. I tried to create a Kraken account but because of my place of residence I'm not allowed to use their service. What is the best place I can buy/trade crypto (lowest fees, best security) in WA state?
Explain the math behind cracking a public key. Is it really safe?
The reason I ask the question is because I was reading about the new google super computer and quantum computers. I know they say 2 to power of 256 is huge but that is using basic technology? The number is basically around: 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 is this really that safe? How long would it take a standard laptop to figure this out and based on how many equations per second? If quantum computers are used this could be possible and make crypto crash right?
About two days ago I bought $1000 of bitcoin, which is the daily limit for Gemini. I wanted to buy more so I tried to deposit cash into my account and be able to get more that way but the transaction was denied and now my Gemini account is showing a negative balance for USD but the money never went through. So now if I deposit the 500 I tried to put in a couple days ago will that zero out the balance and make me loose $500 for no reason? Or will that money just be able to be accessed to trade for crypto?
"Given that this paper is now peer reviewed and approved: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3265157, It would seem that the 'official' Bitcoin wiki is wrong. Bitcoin Script is Turing Complete. Guess @ProfFaustus was right! Is the selfish mining paper also peer reviewed?"
Do we need a new and decentralized "Bitcoin Cash Wiki"?
Over time language has been co-opted, powerful package deal terms were invented to steer conversation and the old resources for learning about Bitcoin (such as the old forum, wiki and subreddit) are no longer trustworthy. Terms such as "full nodes" and "miners" rather than network nodes and SPVs create havoc in the minds of newcomers and generally lead them into the camp of Bitcoin Core. The harm of the latter can be debated (although the majority opinion around here should surprise no one), but the first is clearly a negative and comes back to haunt the larger crypto community again and again. Now that we have a new subreddit and a new .org site, should we try to make a new wiki that explicitly uses the same terminology as the white paper and Satoshi did? I think so. This would help us stay on track rather than falling into the trap of using somebody else's flawed terms when trying to explain how Bitcoin works or making a consistent argument. Let's discuss:
Do people here generally agree with the above and if so what resources do we have to make this happen?
Can we perhaps eventually even make it more decentralized than the previous one to safeguard against future hostile take over attempts?
Who here would be willing to make any small contribution, donate, link or otherwise give ongoing help in the effort to establish the wiki as a public resource?
