FYI fobusinessese who wants to sell PHC for BTC.

I can say as a guideline for the cost of PHC can be the cost to rent a rig and mine PHCOIN on a pool. Some stats:
renting rate from .0007-.0009 (PRICE/MHs/Day) for 24 hours for a 10 MHs miner is .007 -.009 BTC ($4.13-$5.31) when 1 BTC=$590 with the following pool stats:
500MH/s pool hash, 6.3-6.8 Difficulty, expected shares to solve a block of 1700, 8 contributors = 1400-1600 PHC per day or $0.00258-$0.00295 on the low side of cost. So an example would be 50,000 PHC * $0.00258/PHC= $129 and $129/$590 of btc= 0.2186BTC for 50,000PHC or 437 satoshi or 0.00000437 btc/phc

Also Note:
When pool stats are 200-250MH/s, difficulty 2-2.9, expected shares to solve a block of 780, 8 contributors = 3000-5000 PHC generation per day when the network hash rates are low. The unit cost range now is $0.000826-$0.00137 or (0.07BTC-0.116 for every 50k PHC). This condition is rare... usually 300-400 MHs network hash rate is normal.
