This question already has an answer here:
If I want to issue a coin based on ETH blockchain (let's call it BBB coin) which called smart contract or ERC20, my question is about the fees.
is the fee for every transaction of BBB coin will be by ETH or BBB? and how I can control the fees amount when I make the coin by MINT software?
as I saw that many exchangers that accept coins based on ERC20 they didn't deduct any ETH fees for transferring erc20' coins.
