Australian Bitcoin miner Bitcoin Group learned last month that it has finally obtained approval to launch its IPO and begin making company shares available on the ASX. This week, the group announced that those shares would begin trading on February 2, 2015. Since first obtaining approval for its IPO in December, the company has already offered 100 million shares to investors, in an effort to raise $20 million. According to the company, approximately $18 million from that IPO will be used for additional computer power.
