Litecoin has already gone many way and now going for creating new bottom. Just wait for again investment. But, Ripple can be bought as many as possible. Even you buy for $100 now you will become millionaire in the coming year.
i choose LITECOIN, because XRP is only a token. And token should be a utility currency for the ripple network platform which is not the case. So that's why i dont see and real value on XRP. I can see the Ripple Company succeed without xrp. While Litecoin is a coin and has its blockchain. There is a big difference between them. But i don't say that you can't make money investing on XRP. If you know what you are doing, You can make money on mostly every coin or token.
