Yea I also agree. Who will you trust most? Someone who has a lot to lose or gain by holding at least 10k of DMD or someone who has 10 DMD. They might both want to prosper true, but the one who puts money where his mouth is, well that person is more trustworthy to me and I think he will do everything that the projects succeeds, because his money is on the line...
I agree too. More money invested into Diamond project, more risks/ profits investors have, then more responsibility with their votes. I have no doubt about the fact. As a result of this, masternode owners might more carefully vote because they can lose thousands of dollars if something goes wrong with Diamond project. Especially if those ones partially come from their votes (they will never let it happen).
