I would suggest you to invest in ripple and stellar both. Both are simillar projects based upon the idea of global value exchange network and real time gross settlement [RTGS]. Both of them are really popular.Ripple has been increasingly adopted by companies such as UniCredit, UBS, Santanderand & by various banks and payment networks as settlement infrastructure technology.
Stellar on the other hand recently has partnered with IBM which itself is an achievement.
Both coins can show tremendous growth in future and you can earn good amounts of profit in the long run from both of them.
