You should be able to store any ERC20 token there but nothing else.
Thanks. So, just to confirm: I can store several different kinds of ERC20 in the same MyEtherWallet, yes?
Why would you want to risk that?
How much effort is it really to create separate wallets for each coin? I will not do this, because it will become very complicated
when these individual coins gets forked at different stages. Imagine if one ERC20 coin forks and you want to claim the free
coins, like what happened with BCash and Bitcoin Gold.
