@mcc I wrote a lot about this on my (now banned) twitter account a few years ago. Bitcoin is inevitably doomed because the block reward periodically halves (every 2 years or so). At each "halvening" that means the same number of miners suddenly have their income cut in half. A bunch of them will quit or go out of business each time. The only way for all of them to stay is if Bitcoin's value doubles on those events. (Which it sometimes does, but not every time.)
@mcc Bitcoin mining is only profitable if the price of Bitcoin continually rises. Mining companies frequently exit, because it doesn't. https://mastodon.scot/@kim_harding/116034323343458077
