There is a possibility that this might happen. China banning ICOs are one of the shocking and unexpected turn of events in ICO organization. Frankly, this really affects now the pricing of bitcoin. There is a also a possibility that the neighboring countries of China will be aware of this ICO. I hope they should consider and investigate and give chance for the ICO organization to explain their side and from that they should make a final decision.
I agree with you that all countries have the opportunity to make the regulation prohibit ICO for the same reason as the regulation made by China unless there is an ICO project in a country requesting the government's approval to make ICO and part of the profits left to the government I do not think the government will interfere about ico again.
