I find current Litecoin price unsustainable and have to urge caution when buying at this level. The only reason that made price pump 500% is the halving which is two months away and all these people shilling like madmen.
If you don't want to cut your losses sell while still on profit. I don't know who exactly will buy this coin or why it exists besides speculation. I don't see comments covering anything else besides price so I guess it has no other use. Even when at 20$ Litecoin had little appeal. Just move into Bitcoin and spent your time on the real deal.
