Hello.
Your project is very interesting for me.
Citizens of which countries can take part in your ICO?
Hello.
Participating in ICO is possible from almost all countries but for some rare exceptions (e.g. USA).
Still the best way to find out if you country doesn't restrict cryptocurrency is to consult a lawyer.
My country is not banning cryptos but there is some rumor that authorities want to take control of its usage

The same situation is in my country as well. It's tending to begin banning.
I guess that's because your authorities want to promote your own "national" cryptocurrency.
You may be right. But it means that "our" cryptocurrency will be strong in our country and still we'll be able to trade it on exchanges.
Many new project starts on the basis of NEO now. So we won't have ICOs shortage

And the existing projects can issue parallel coins on NEO.
e.g. "HAC2"/"NEOHAC"/...

Interesting idea. Just like in Venezuela. One coin had success and they decided to announce one more
