It all how much investment capital you have. If you can hold hold, as POWR right now is undergoing a correction, but I think it will go even higher...unless Bitcoin goes crazy again, cause if that happens, then most of the ALTS are going down the drain.
with 1,000,000,000 POWR total supply and still 360,482,334 POWR in circulating supply, market price is about $1,62 USD
there is already much exchanger that can process transaction of POWR token
with bittrex have 43.90% of world POWR volume transaction
I think this token will grow more but when team release their token into market, this will bad news
if price can hold aboce %1.8, I think it will grow more until USD $3
