BTC or Litecoin!
It's totally depend on your choice. But if you want to get much more profits then I recommend you to invest on Litecoin. Cause Bitcoin is a stable coin and you can't gain much profits by invest on it. So litecoin is the best choice.
I recommended to choose Litecoin. now, Litecoin have high price. so with high price we can get many money for future.
Litecoin have development continue strong, this moment is good to have Litecoin and hold Litecoin.
