Great article...I got sucked into this program about a month ago, bought a $500 pool....based on my calculation in Excel and payouts to my wallet thus far, it will take me 1186 days to get my original 0.198 btc back. Seems like all the positive reviews are based on the price of btc going up in US$ terms. My conclusion so far: you're make more US$ or whatever fiat currency if you simply buy bitcoins with your fiat and hold them.
