In my view the first thing we need is crypto that are completly untracable and truely decentralized exchanges.
Once that is in place people won't have so much risk and everyone willhave the choice between using the government currency or a decentralized one. I suspect most sheople will be using the government one, especially if the other ones are made illegal, but who knows.
The IMF thing scares me alot more than China or Putin making it illegal, they could make it illegal worldwide, I do not think that the enthusiasm of the witch Christine Lagarde is for decentralized cryptos rather the mark of the beast government controlled digital currency.
