If you can manage huge money ( without losing) than you need to buy Bitcoin. I don't know why you need to choose in this two options, out here you can get more profit from other coin. But Litecoin is good and also coinbase supporting.
I agree with you, why litecoin I wonder also. If you want to invest to just big projects, you must look to Neo, for me it can be more profitable and more trustable project and team. Also ethereum can also be considered, it is very cheap from few months like every altcoin.
