For me selling masternodes is the same as ICO. There is no guarantee that you can lose all your money. It also occurs that after being listed in an exchange Dev drop all your coins and this is the end, invest thousands of dollars and only recover a few cents. Either way, you lose.
I'm not saying that this is the case because I can not know but having a POW phase or better, a POW percentage would have been better and I would have entered the game. I hope you are serious and do not make people lose money.
Good luck to all who dare with this
