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.
I experienced this, too many useless tokens in MEW wallet and if I do this, then I just throw away my ethereum just to transfer my useless token. I prefer to let my useless token in my wallet and not get my hopes up on coins like this.
