Where is the rule
"ABSTAIN do not have a vote"
Why we need to count on them?
I think, to be nimble, in the future, votes will work on a quorum or something. But for this first vote, we want it to be a popular vote (meaning, a majority of all the Masternode owners need to feel good about this idea). Frankly, I'm shocked that it's taking so long to get half the MNds to vote. Where is everyone? Is it too hard to do? Perhaps there are that many people on the fence, but I can't imagine there are so many out there without an opinion!
It seems some 1,395 MN did not vote. Otoh himself has about 50% of these MNs so if he did not vote yet, herein you have a half of your answer, And there are other big holders, one with more MNs than Otoh...
I dont know where you get your information but that is not correct. Otoh is the #1 holder there are no other holders with more nodes, plus he invested a large amount and bought all coins on the market.
