Is it still possible to buy shares for 1BTC from the securityowner? Maybe with the stated plus of 5%? And how long before the start of hashing, so start of paying dividends, buying of shares for 1BTC will be possible? I know there are offers at the market but they are all higher.
The IPO is officially closed. However, if you seriously consider becoming a board member by going through the bulk purchase option, please contact friedcat. There is still a pile of shares which didn't get sold. However, using those may require the approval of the existing board members, since it effectively dilutes the existing shares. (currently a share is worth more than 1/200,000, because not all shares were sold).
