For those saying that crypto is useless, here is a great use case. Authoritarian governments are currently preventing individuals from moving their property across borders. Crypto fixes that.
Maybe at that point there would be two worlds of crypto: you can trade it on the above-the-board exchanges, but can’t move those coins out onto the blockchain in any meaningful amounts. Or you can have it on the blockchain, but you can’t convert it to USD/EUR in any meaningful amounts unless you find a private buyer.
In fact these separate worlds already exist — it’s not like most Coinbase users ever interact with the actual chains, they just trade inside Coinbase’s SQL database. But a lot of the appeal of crypto is about theoretical possibilities, and government regulation can put a real damper on that enthusiasm.
