Price per share @ IPO: 0.1 BTC * 12 dollar = 1,2 dollar/share
Currently mined blocks: ~284
Currenly mined BTC: 284 x 25 = 7100
BTC / share: 7100 / 200000 = 0.0355
Dollar / share = 0.0355 * 34 = 1.207!
So actually we mined our IPO price back about an hour ago!
*I know the exact mined BTC are not 284 and after IPO price is reached the BTC have to be devided my 400000 but this is pretty nice after about 2 weeks of mining (and the recently rising Bitcoin price )
I paid for my shares with mined BTC, not with $, so far they mined 0.02xx BTC back as far as I am concerned....
Needless to say, that is better than most Bitcoin investments !!!!
