Re: ICO forbidden in China? Will same thing eventually happen in all countries?
Yes it could happen elsewhere.
I think we must not lose sight of the fact that Bitcoin and cryptocurrencies are creating a new economic system which is a thread for central banks, state institutions and so on. And states and banks are still very powerful! So, they could present cryptocurrencies like something bad, dangerous, not safe, and they could make them illegal to protect themselves.
I invite you to read this interesting point of view: http://www.marketwatch.com/story/bitcoin-ether-and-other-cryptocurrencies-may-be-seeing-the-beginning-of-the-end-2017-09-06
You will better understand that actually it will be difficult to keep your investments safe if states decide to change economics rules.
I think we must be careful : China has decided to regulate ICO's according to its interests, Russia wants to forbid cryptocurrencies (and then ICOs) for "people" and keep it for traders and "specialists" in economy. Thus, we have here two huge oriental economies (the most powerful actually, in the most authoritarian countries by the way) who are deciding to take ownership of the financial power of cryptocurrencies. I don't look it favourably...
