There was a time in 2014/15 where paying for goods with cryptocurrency was becoming popular. Its at this time when coincidentally, regulations towards requiring PII was instantiated in the US, essentially freezing most in/outroads of fiat. It was the end of traded goods for crypto. This coincided with many of the original arguments on how & whether to increase transaction capacity (bitcoin cash debate), we see who influenced these (core devs/miners/exchanges/regulatory reps sponsored by banks) and how they played out in hindsight. I'm not saying this was a coordinated effort, rather an oversimplification of the natural response from traditional fiat participants towards a threat to the 'status quo' at the time. However, this shift, happening at the most crucial tipping point, is what I believe to be the end of the ideal 'cryptorevolution' and instead a new compromise with the existing system. These disruptions were 'successful' But.. you know... thats just my opinion.. man...
