sometimes i receive random erc20 token too
though i dont know what it is lol
and the amount is big tho, well, since the people could write erc20 with closed eyes,
its easy too to just throw away the token
Those amount isn't big.
The quantity of those tokens are big but in real value, it has nothing to do with its current market value. You can't even throw away those tokens unless you want to spend some gas for those thrownaway tokens that has been passed to you as a way for them to be recognized.
