All crypto-currency have volatility, so bitcoin isn't different. I am assuming price won't touch $20K on this year, but just remember, anything could happen. Just need another revolution to cross previous all time high. But current rally isn't indicating to touch ATH at the moment. More new investors should join to bitcoin community somehow to make a revolution again. To be honest, bitcoin much more popular to community for that's volatility, and it will remain.

Regarding country those are banned bitcoin, actually they are worried about their centralized system. Volatility isn't much problem in my opinion. Governments always will try to control everything especially if related with money. You can see most of worldwide governments allow centralized online fiat currency like skrill. But their main problem is decentralized system because that's out of control from some organisations. And it's true if they unban bitcoin then we would see that reflection on bitcoin. Price would go up that we didn't imagined before. Let's hope some days we will see that worldwide governments unbanned bitcoin.
