He got multiple hundreds of thousands on day one, that much is obvious.
All the estimates I've ever seen from both detractors and promoters put it at between 150 and 250 node's worth. Make it 3 or 4 if you like.
In addition, he compounded those gains by running masternodes when the return was around 20% per year
1st = 250*1.2 = 300
2nd = 300 * 1.2 = 360 (Way excessive)
360,000 / 7,100.000 = 5% at best (if he's held the whole time and never taken any profits during the 4 massive spikes that have occured in Dash's history).
Biggest holder was actually Otoh - and his were bought, not mined. He was way past Evan at around 400 odd nodes which has served as a liquidity supply for OTC sales for the last 2 years. He's now down to around 77 = 1% of coin supply and no longer trades.
security model....which we all know is a sham.
So much of a Sham that it's survived 3 years plus a recent DDOS attack without blinking despite a steady queue of green-eyed detractors making claim after claim of one exploit on top of another and how "easy" it is to "simply".....(don't think they've not been trying).
