PIVX is a good coin but I think it's better option... POSW = STAKENET.
POSW is in the rebranding process which at the end of the month will have a fork from PIVX.
Adding to PIVX value: Supported by Ledger Nano S, Trussless Proof of stake and it will have a Staking platform service as the old POSW had earlier but much professional and better design... big potential imo.
