You may consider blocking US investors since this would be a security.  And the SEC seems to be frowning on obvious securities. Your biggest problem will be with the liquidity of your token.  If you are only raising 1.2 Million.  You may find it hard to find buyers and sellers if you list in multiple exchanges.  This will also be a drawback for any potential large investors, especially if they have the ability to buyout the entire raise.  So with limited/no large investors, you will need to think about spending 100k-200k at least to advertise to the smaller investors.
