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.
All these pump and dump coins are like gambling with the money. Bitcoin however is a very different crypto, its level is much more different than all this and it is highly accepted and traded as compared to other crypto. OP please don't regret your decisions as living in past has helped no one. Stick to btc, that has much more scope in future.
