if you want stable investment go with BTC
Yup...and with the Winkelvoss ETF comng up soon (ish) BTC could rise like crazy. Maybe.
NXT is always a good bet (

), and I'm pretty certain that SuperNET and its associated coins (BTCD/BBR + others...) will do very well.
I also have a vague gut feeling that NxTHorizon is about to go to the moon......and CMC agrees with me so far this week.
