In the pre-sale or even in the main sale, must validate the investor's data, ie will it be necessary to undergo some KYC validation?
Woow, maan! What are you talking about?
KYC validation?
This is no any ICO, or something else

All you need is bitcoin and roco-wallet I think, without any verifications.

All this KYC validation crap used on the top-exchanges like bittrex, bitfinex etc...
