1.9 coin in each block i have a total 246 coins
Assuming 4 hour maturity and getting a reward in 24 hours.
2 coins @ 25% annual = .5 coins annually divided by 365 days = reward of .0013 minus MN fee = .00045
@ 300% rate = 6 coins annually divided by 365 days = reward of .016 minus MN fee = .0054 coins
Right now MN are getting knocked off line so that may be screwing returns up.
Approx. numbers but, maybe I am missing something
