I have seen ICO's that block mostly USA, North Korea, China and some Middle East countries. Also i have seen ICO's that block more than 10 countries. So its confusing for me why some countries are restricted and why some countries aren not restricted.
- How they decide what countries they are blocking?
- What's the difference between ICO's that block say 4 countries or more than 10 countries?
- Does this come into factor when i am investing in such projects?
No, not literally, some are being driven to be blacklisted based on the jurisdiction that a country has. ICOs and projects have nothing they can do about it but to respect the fact that they are not allowed to implement their services there. Also, it is a factor when you are investing, make sure first a project is allowed in your country.
