Hello,

for the website kind of an ICO website is it better to  use a ready made template, there are so many nice ICO websites out?
 
How can we build in an affliate System into a coin?

means, you buy a token, then if you use an ICO website, you might get it in there or you get it send to your ERC 20 walllet.

HOW can be build in that i can invite people to the coin that getting commission, is there any way to safe wallet address as username and relations in the smart contract?
like wallet user A has recommend user B and now whenever user B gets profit share coins, than user a will get a part of it into his wallet?

maybe an external database that safes this and the smart contract reads it?
