Ripple is bad if you buy coins based on their ideology and support Austrian school of economics with all this free market and decentralization stuff. If you don't really care much about it and want to earn money - ripple's very promising. Ripple works with banks, so that they don't die as cryptocurrencies become more influential, and it's good at what it does, so it is very likely to grow with time. The current price is obviously still very cheap, I am sure it can be worth about $10 in a year from now.
