I think most likely, it will top out at around 1000 MNs is my guess.
I'm guessing around 300 max, because those that would've had tens or even 100+ of nodes with the old 1000DRK=1MN system will now just have 1.
That said, could someone please tell me why the multi-ticket masternodes was a good idea again?
Multi-ticket was built for whales and possibly the exchanges. So, I stick to 1000 to 2000 MN guess, as much easier for whales and exchanges to build MNs if multi ticket is implemented in current form.
