I can only talk about Russia here.

Russia hasn't banned Bitcoin and isn't yet planning to) So I would say it is quite unlikely that more stringent measures will be introduced.

However, it's also true that the Kremlin has recently devised regulations that apply to cryptocurrency users. Namely, the government is planning to make all miners to register with the officials and pay taxes, while the ICO practices will be made to conform to practically the same standards as do IPOs.

In a nutshell, Russia is only figuring out what to do with bitcoin, and the government still allows people to keep cyrptocurrencies. Right now the Kremlin wants to see whether it can control it bitcoin users, while also gaining fiscal revenue from them. Whether this will work is another question, of course.
