He didn't start out right , now he definitely need more explanation. My question is are you using asic miner, FPGA or GPU mining at this point in time? buying and selling BTC is trading BTC, but now you are Mining BTC, a different ball game very technical, alex if not mistaken is selling and buying btc, not sure he is into mining? you need to get your compass right..

Actually nothing is confirm until sample chip and BOM arrives. Even BKKcoin is not sure if all of his parts, setting, calculations or analysis is correct? they have to test and teak when the sample chip arrives..
