Ripple isn't a cryptocurrency. Isn't Decentralized. Not to mention, is being supported, pumped and hyped by large banks. If your sole goal of the recommendation is to make money, then I wish you luck.
Since you used the word "Invest" in Ripple. That is concerning. It's not an investment at this point.
Yes, Ripple operates on an open source and peer-to-peer decentralized platform that allows for a seamless transfer of money in any form, whether USD, Yen, litecoin, or bitcoin. But peoples says it is second biggest curreny after bitcoin..
