Let me clarify this: Just because the US SEC wants something doesn't make it happen on the internet. They can do things with governments and companies, and that's about it.
If some random hacker in Ukraine decides to use a ETH or BTC or smart contract or create a new coin, the SEC isn't going to be able to influence that. There is no point of control there.
And that much better option is to just use the regular banking system.
Cryto currencies have massive costs and disadvantages, and there is no point at all to them if you take about the fundamental premise and purpose of them, which is decentralization.
