Siacoin is the choice for the many miners due to its less difficulty rate dude. I see many people invested on siacoin in the trading sites as well. You can invest on the siacoin if you are looking for term profit.
I am 100 percent sure that sia will rock with in some months or in a year. I can compare this coin to Ripple's growth. Even this coin stable around the same cent level value and waiting to touch the peak soon.
