So even if difficulty would remain the same, thats 5 weeks of no reinvestments. Of course difficulty did just change and is bound to change at least 3 more times before the loan is paid off, so you are probably looking at closer to 2 months of no reinvestment.  Current hashrate of petamine is 1.3PH in a network of ~90PH, or 1.4%. By the time the loan is paid off, it will be well below 1%

As for the "impressive" and "hefty" dividend, maybe Im missing something, but 0.00209952/0.0975 = 2.1% of the IPO price. The network is growing by >7% per week. Any math geniuses want to guess how long it will take to earn back the principle through divs? Thats right, forever and then some.
