Since I'm an American, I can't take part in your ICO. Do you have plans to allow it in future?
Unforunately US and Canadian residents are not allowed.
Any more restrictions?
No there are no more restrictions.
KYC is mandatory?? what documents do I need if I wanna invest?
You have to pass KYC procedure in order to receive Zichain tokens. You will be required to provide identity documents (passport, driving license, or national ID) and documents confirming the residence. A KYC-system will be accessible with the beginning of the TGE. By that time you will receive an email with the instructions. You can go through the KYC procedure before or after a purchase of tokens, but at least 7 days prior to the end of Token Sale. Tokens are issued and transferred immediately after the successful KYC verification and purchase.
