Any country will ban ICOs because it is not a legit way to raise funds sooner or later,South Korea and China went ahead and did it. ICOs might come back if the company/organisation ask the specific government of the country they reside in to raise the funds in,but still you cannot be sure what will happen. Sometimes ICOs are scam and sometimes they are good for investment. I don't know what will happen in the future when ICOs are asked about. Just want them to be there since I personally get benefited some times.
As I know the banned only BTC, not ICO. But I agree with you, they should make rules for the international ICO's regulation
