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?
Do they need to be 125K in the same address? or just in the wallet staking?
They just enable the stake rate for any address in the wallet. Which is now 100% for all the prime activation keys
