Evan does not own 500+ nodes. Otoh our largest investor currently owns about 430 nodes as he divested a big portion of his nodes in favor of more distribution and a healthier network, also giving new whales the opportunity to buy in. Having said that, I don't see why the minimum age for a proposal could not be changed to 48 or 72 hours to always give the network more time. I think that is a really good suggestion.
How would you know?
I ran the numbers 6 months ago, but I estimated Evan should have mined 750,000+ in the first 24-48 hours with the hashrate he himself claimed to have at the time... that's 750MNs already... (not that he necessarily has them online right now)
Then they start collecting 50% of the mining share as masternodes, he should have 1000+ by now...
