what about the speed of repayment on the principal? Does that slow down like profit? stay the same? or speed up?
Under the same diff, in case of 1 BTC investment, PPS payout, mining revenue is 0.01077264BTC in day one (1), the profit is 1BTC* (0.7*10^-8)*(1*24*3600) =0.0006048BTC, then unpaid principal after the payout distribution in day one (1) is 1BTC-(
0.01077264BTC -
0.0006048BTC)=0.98983216BTC.
Day two (2), the mining revenue is still 0.01077264BTC, the profit is 0.98983216BTC*(0.7*10^-8)*(1*24*3600)=0.00059865BTC, then
unpaid principal after the payout distribution in day two (2) is 0.98983216BTC- (
0.01077264BTC -
0.00059865BTC)=0.97965817BTC
...
I think the speed of repayment is up, under the same mining revenue condition, the profit is less due to the
unpaid principal becoming less as the contract goes on.
