I have some dead tokens in my MEW wallet that I don't know what to do with them.
and what to do with SuperCoin's i put 1 000 000 of them in my notepad. Sometimes in good mood i add another zero to it. Im Supercoin billionaire 
sorry about that little side note
, i have bad news for you, they are worth nothing. When something is worth nothing and you can't use it for anything usefull just leave it, forget it, let the loss motivate you to invest better next time for example in one real actually revolutionary cryptocurrency. Its called bitcoin.
