I've just discovered PETA while browsing Havelock and am interested in learning more and possibly investing.

I did a bit of math, to see how long it would take to pay back my investment by earning dividends:

PETA Last dividend: 0.00063172 BTC/unit/week
PETA Last price: 0.07200201 BTC/unit

Weeks to recoup unit cost: 0.07200201 / 0.00063172 =~ 114 weeks = 2.2 years

Even if the dividends were to double, we are still looking at over a year. Is this calculation meaningful? Is 1 - 2 years to recoup this investment considered good, bad, or so-so? What am I not factoring in or taking into consideration? How are you seeing the value of this investment? 

I guess I'm questioning this because most mining operations expect to recoup their investment in months, not years.
