The issue is that with past Crypto runs, not everyone knew about BTC/ETH/ETC. This time around, literally the entire world has heard about crypto and has been pitched to buy, up to having Matt Damon calling you a coward for not buying during the Superbowl. So when the price of BTC finally stops at somewhere like $800 a coin, people aren't going to be buying anymore. There's no magic left in the system. The whole "it runs on vibes" thing is the only true statement that backs the price of BTC given that it's a negative-sum game.

When the vibes run out the miners leave the hotels fold the bars close and the whole circus leaves town. Coinbase will be a ghost town in a few years.
