Good choicement mate especially the power ledger. POWR is a good project that supported by Australian Government, good for long term investment. I have some of POWR too. My other favourite picks are BTW, CRPT, TRAC, Storj, GNX. CRPT is i strongly recommend to buy as the price now is half of the ICO price and still not listed on the official exchange.

But for me, the most important to choose the altcoin is not about the price but the supply.
