In my opinion, you did the right thing. You should not look at the current LTC vs BTC exchange rate. In the long term, the real worth of Litecoin will be close to zero. Just do the calculation yourself. Right now, there are hardly any sites where you can use Litecoin. Litecoin is dead now, and these temporary pump and dumps will only help to delay its demise.
could we say that the litecoin pump is just temporary do to the halving ? maybe a pump group trying to have leverage from their accumulation vs what is coming to play now.
