So do you have a way to hide it or delete all the coins from your wallet?
There's no way to delete or hide it on your wallet but I think you are irritated looking at those coins through your wallet. I've read someone suggested this before that create another MEW and then send those useless coins to that wallet and leave that new wallet forever.
Problem solved.
This may be a bright idea but I do not think that it is worth wasting gas on just to move some shitcoins from one wallet to another. Why not just start afresh and open a new ether wallet instead?
