You can sell them on Hitbtc, register there and sell them off.
good luck
I will do some research myself, because I was wondering about XEM and ETH; Are you able to give me the bullet points on what makes the XEM less promising in the long-term (or even short-term)? I never knew Hitbtc was a real site, I always get email spam from them and thought it best to avoid them. I'll take a look now, you don't think DimCoin will last or increase in value then?
What specifically about their road-map discouraged you BTW? Was it the planned release in certain countries, or something along those lines? Limited distribution, or did something else stick out?
Still taking offers here, obviously, but will be considering dumping it on HitBTC if no takers.
