The same for n2 but wasn't there quite a few large mining accounts already? So wouldn't the buying of steempower need to be quite large and back in 2016 the price was high. So n2 let those miners and their circles/ trails benefit massively with very little risk anyone would threaten their stake.
I wasn't here then but I can't imagine when some accounts mined 5-10% of supply +stinc anyone willing to buy in at that point heavily.
Edit: not my area either so I might not understand :D
