It seems to me not correct that the price of most ERC20 tokens depends on the price of the ether! What do you think?
One hundred percent NO NO NO!!!
there are so many ERC-20 tokens in the market that can be exchange with BTC... most of them.
those erc-20 tokens that depends with ETH are those who dont have exchange but FD and ED...
there some ERC also with USDT...
