Crypto market is not about getting RICH. Those "hipsters" who think it is, are all crypto newbies and they make that price spike last year. Cryptocurrencies are the future, but not anonymous ones of course. Just because they are the future, doesn't mean we will all get rich, NO. But they will still exist, and you will be able to use them.
When on the market stay only people who see a real value of crypto, value in new money transfer system that CAN be anonymous and decentralized but NOT necessarily then price should be much more stable.
Many people joined cryptos just to make huge money in short period of time, but that is not a reason why cryptos was created.
And just to say, you can't ban crypto, there is no way for such a thing. That's the reason why they are trying to tax exchanges, of course, there is also another way for that
