STABLE aims for the first Refund & Payback Crypto assets exchange. The previous exchange system did not pay the corresponding coin owner for the P.O.S Profit or Masternode Reward profit taken by the exchange owner. We thought that that monopoly of profits should change. We intend to return other profits(like pos reward or masternode reward) to the parties reasonably. You can have the effect of running a Masternode or POS server simply by placing your own coins in the exchange's personal wallet for transactions. Of course, you can make transactions for the coins at any time.
