Let's do some math:
Today's FAC sell price 0.00000305 BTC
Multiply by 166000 = 0.5063 BTC
1 BTC about US$633
166 hours work to make 0.5063 x $633 = $320

Personally ... I wouldn't do it, unless I could figure-out an automated way of some kind.
I heard that in China, where labor is dirt cheap, they had rooms with tens of workers sitting at computers, every worker redeeming a token every hour.

All this MAY (or may not) pay off some day... we'll just have to wait and see!
