Here in the U.K. it is not against the law, but our government did advise against investing in ICO projects.

Due to this some ICO projects have stated that they do not accept investments from the U.K. but if it is a simple Ether ECR20 token and do not need to register an account, then not sure how they can stop anyone!

But did not think that any country has actually passed any laws to stop ICO investments? Maybe I am wrong about this?

But do check the laws for your country and let me know if you find anything :)
