I tracked the unpaid MN a few days now. Around 25% of all MN are without rewards. You have to wait around 5-6 days with luck - it looks like it´s going up... . if you need to restart the node or your VPS you´ll set to zero, this is what happened to me and what really sucks!
I really do not understand why there is no clear statement concerning this problem. Maybe they sees no issue, but this also would be a statement and everybody would know and that there are no improvements planned. It is okay to wait, but nobody can (or is willed to) give clear answers. You´ll only hear: "Be paitent, you need to wait, deal with it, yeah there are too much masternodes around". Yo see people asking the same questinons day by day and this is no inpaitend child behavior. They´re uncertain and when you ask you receive facepalm gifs... 25% of the masternode holders support the project and are apparently not taken seriously.
By the way, I´m waiting now since 7 days...
So guys, if you want to invest consider well
