If that would be illegal, you can still find a way to trade crypto as it's anonymous, you can send it from country where it's legal and let them do the job for you, actually you can always find a way if you are a crypto enthusiast. Maybe I'm just lucky that crypto is legal in our country but I'm pretty sure some other countries where cypto is illegal are still enjoy crypto in ways they can avoid getting caught.
Most likely it is. It is very difficult to completely ban the use of cryptocurrency, there is always a way to use cryptocurrency. I think now is the time when the governments of the countries understand that the cryptocurrency cannot be stopped. It's like a snowball that has gained acceleration and now it will only grow and gain momentum. I do not think that they will now prohibit the use of cryptocurrency. Most likely, the regulatory issues will be tightened.
