So I was wrong, there is apparently a minimum. Which makes the leaked keys somewhat less dangerous - to make use of them someone would have to spend $20k or whatever the exchange rate is now.
Or someone would have to be in posession of 125k coins like BTClend.
Currently there are 58 addresses with over 125k in their wallets.
50 of those, 49 after last night, would be Prime Nodes themselves. That leaves 9 addresses with over 125K?
So if you made those 9 now stake at 100% additional then you get:
125k min @ 100% year = 338,393 per/year compounded daily x 9 wallets = 3,045,537 coins
3,045,537 - 1,125,000 original xpy in 9 wallets = 1,933,037 new minted coins per year (100% compounded)
or 161,086 per month
or 40,271 per week
or 5,753 new coins per day!
That could put some hurt on your investment.
(math might be wrong, was never good at it)
