"Block time is 2 minutes, so 1000 block is about 1,389 days."
hate to tell you this.... but your math is shite...
and you are a "developer" ?
circuithead, If you would have done the math, you would have instantly realized that it was a typo by the developer/admin of this thread.
1000 blocks = 2000 min = 33.33 hours = 1.389 days
he made a typo and wrote 1,389 days instead of 1.389 days. You can excuse him for that and let him focus on more important things.
