LTC is an old altcoin ,, persist until you get profit is better than having to sell it now. and you also do not have to worry about holding ETH, as you can see for yourself, many ICO providers are using ETH as their token base. everything will be back to normal, patient for your benefit.
But the thing is ICO now is in danger, China bans ICO lately and of course, the price recently going down due to this effect especially BTC and ETH, I hope this will not cause too much on BTC price. And don't underestimate LTC, LTC proves us its foundation even its an old coin it just increases recently but decreases shortly with starting this month, so there's a high chance that LTC will bring back that price again. And to OP where did you bought this coins? what exchange you used, better use Bittrex for good.
Just hold your coins and set a high price so you will get much profit.
