A few things:
- The scales of the first bitcoin bubble and the last one are very different. The last one created, literally, billions of value for the holders.
- A defunct bitcoin exchange can not "create" billion of dollars of wealth. That does not make any sense. People who bought early and sold when the price appreciated didn't make money from an exchange who went bankrupt but from people who bought higher.
- Bitfinex seems to be doing fine from a price perspective. The premium is gone. The AG doesn't seem to be interested in driving them out of business but rather regulating them.
- The era of the single exchange is gone. Bitfinex is a key player but there is no player holding the whole market. There is also an active off-line trading market.
- A bubble is usually the result of a FOMO-consumer market.
Some people are going to hate crypto and that's fine. But my guess is that crypto will stay here for longer and will mint more millionaires.
