What are your plans about bitcoin and LTC? What's your main goal, are you planning to hold for a longer time or you want to become a short term / day trader? Those two coins you are holding are good to hold and you just have to do nothing with it. But the idea of buying some more bitcoins is what you must do. As many news are coming out bitcoin's potentially growth is there and after some years the price today will be very far from the future's speculated price.
2nd option. Hold and hope for the long term (but not too long because as one said, at long-term we will all be dead 😬)
Yep hold for longer term but not that really long. Beside on what I suggested on what you must do is also when you see good progress with LTC or you are able to earn some good amount then you just simply sell some of your LTC and the profit you'll be getting there is the one that you'll be using for buying another bitcoin. This is being done by most of the traders, they are selling their alt coins for bitcoin.
