As we know nowadays everybody uses cryptocurrenies and specially Bitcoin in their trades and criminals too. China recently declares blockchain illegal in that country, How likely do you think is that other countries ban it?
If they start to ban it, what would be happen to bitcoin price?
For now I would say that it is very unlikely for countries to make bitcoin illegal now that they are beginning to notice it's potential and threat to them as well. I am sure that many countries right now are planning to use bitcoin to their advantage by adopting it early, like Japan. They know that if bitcoin goes mainstream, they would greatly benefit from it as first countries who adopted bitcoin. For now maybe they are planning to regulate bitcoin to some extent and are making a protocol dedicated to it.
