I don't think anyone here who has held shares would disagree but this isn't about that. IPO investors who entrusted him with 500 BTC (~$5000 at the time) for a board seat (5000 shares) are now millionaires, go back and read that for yourselves. However, the question that many people here (speculators and soon-to-be shareholders) are wondering:

Q: Is it more profitable to

1) just hold BTC
2) spend BTC to buy mining gear that is "ahead of the curve"
3) spend BTC to buy shares in mining company that develops and sells their own hardware

It is highly recommended that those who decide to partake in any of these options to do your research, or you will just give away your BTC.
