both tokens are good to invest. They are one of the most elite tokens out there, ranking 3 for ripple and 6 for litecoin. Don't get a mistaken, even though ripple is in number 3 doesnt mean it is better than litecoin. Look at their differences, look what are the exchanges they were in. Then choose what is the best for you. But for me, I will go for litecoin, it has lesser supply, and as the market says, the lower the supply, the higher the demands.-
