Buy Ripple, that is definitely a good call. I personally like ETH even though many doubt that it will survive the next year. Also, find some new unknown project to support that is worth the long term investment and support. My choice is BTCN. It is quite unknown and low ranked, but it has excellent project and names behind it. It already has a strong, active community and is present on several exchanges. With the right moves and active support, I believe that it has a great potential.
