You can't really have a second one anyway it's an initial PO. There really was only one, the 'second' was just a re-write and offer-price of shares was adjusted due to market demand.
Well there was an IPO for AMC at .0005 which went towards buying Avalon chips etc. Then the second IPO at .0025 was when the company was restructured so that ActiveMining would become the parent company of both AMC and VMC. The price was not due to market demand. It was the amount that the remaining shares of the 10 million had to be sold at to reach the $1M NRE for eASIC and only ~115,000 shares are left out of the 10,000,000 public shares.
