Approximately 60 blocks per hour!
Now #12400, growth stage until 20100: 7700 blocks more / 60 bph / 24 hours a day = 5.35 or little more than 5 days of stake.
As more people stake, the blocks go faster? I've heard of blocks taking time, etc. being mentioned in other threads. Is that when no one stakes? Can any tech guru clarify?
