When i look around at all the positive innovations cryptocurrency has failed to deliver, it really does seem like they invented a currency exclusively useful for doing crimes.
I got into bitcoin around 2011ish for some time. I was never a True Believer but I was a 'soft believer'. At the time, when people asked me if Bitcoin is the future I would always say "I think it or something like it will be very useful". Fast forward 10 years and there's been no actual use of crypto. No killer app. No disrupting the finance world. It seems to be used exclusively by smart people as a means of extracting wealth from people who don't understand it.
Cryptocurrencies is one of those things that makes me embarrassed for the whole tech industry. I wish it was the only thing...
