I can only advise ardor. it may have pumped already (like 99% of all the alts) but before end of 2017 it will atleast 3x when the Mainnet launches!
Mark my words...this is gonna be HUGE!
So don't miss out on it!
3x isn't really huge in crypto.

And SONM seems like it could raise much sharper in the same time frame. Always good to diversify though, so might as well pick up both.
