The price will go up and down as it does today. but probably it will be less volatile. price for 1 btc will be not less than 20k.
However, it's also possible that more governments will ban it. but I hope crypto will become a mass adoption in the end. but you never know. we will see. anyway, I'm excited about the future of crypto. If they are worried about their own economy and have some common sense they will not do that. In those countries where bitcoin has been declared illegal are those with small economy and are poor compared to other countries. Moreover you can always use anonymous services to help yourself stay anon and not be detected by the agencies if you decide to use BTC while it is banned.
Well, no one canbe 100% sure about its future. We'll wait and see.
