So philipma did you get more th.
Yes I now have 10 th
I also think the interest rate is not 25 percent or 12.7 %
It could max at over 12.7% percent since the contract is .00000008 per second per 1btc but the .000000008 slowly declines to .000000001 as you get paid off.
the average payment is 0.000000045 even this could vary if you had tremendous Bad luck early then really good luck in making blocks late. then your contract pays off better then 12.7% but I think the floor % could be said to be 14%
the max could get near 15-18% but not 25%
floor number is
0.00000000045 * 60 * 60 * 24 * 365 = .141912 this is most likely the best guess.
but it assumes a lot
1) the contract pays off in 120 days with very stable luck.
2) this means the avg pay off per each second of the contract is .0000000045 not .000000008
3) Some would use .000000004 not .0000000045 as the average then you get 12.6%
So the minimum could be said to be 12.6% to 14.1%
max is harder to estimate, but will never be 25% since magical impossible luck is needed for that to happen.
basically make almost no blocks for 100 days then make tons of blocks the last 20 days… this would get you closer to that
25% but the math would be near impossible and antpool would go broke due to the 100 day streak of terrible luck.
