Hello. How much time will it take me to buy tokens of a project via your service?
I think that very little. You will simply need to review the information, click a couple of buttons, select the number of tokens and the payment method.
And what about undergoing KYC? Or will it be optional in ZILLA?
All members of ICO teams will undergo full KYC. Users will undergo basic KYC, and for projects that require them to provide more detailed information, then the user will need to.
