Is poly looking at having masternodes and going to pow/POS?
I am not sure really what the above masternode has to do with poly other than paying people out in polytimos Coins while investing in other coins.
Right now we are @ block 21.130 so there are no master nodes for this coin, @ 80.000 POS/POW system is coming online
As first project POLY is hosting master nodes to other viable coins. Meaning, that the community member gathered the amount of coins needed for theese master nodes and the POLY team has created nodes and pay out to the contributers as per share in node coins and in poly.
Hope this helped.
