It is a senseless thing. Countries cannot regulate a decentalized market. It is impossible. The more they try to do it, the worse it gets for them. In another 6 months, I am guessing, there are going to be few more decentralized exchanges....once the exchanges are all decentralized.

As for mainstream adoption, the only thing holding people back is that cyrpto is still a bit complicated to use and a rather unsecure. The industry needs to solve those problems before it will reach mainstream, which I believe it will.
