However, A company dealing purely in BTC is ultra-risky compared to traditional investments. Therefor, a P/E of 10 seems unwarranted.
Well, normally, companies that have large growth potential have high P/E's (15-50x range) and companies that have little growth potential have low P/E's (5-12x range).
Based on its growth potential, SatoshiDICE should have a higher P/E than what I've priced it at. With that said, I understand all Bitcoin companies are high risk and thus perhaps a lower P/E is warranted, so that's what I did. I think in any case, the argument that at 10x P/E ratio is "way out of line" is silly. It's a conservative valuation for one of the most successful bitcoin businesses that has ever existed.
Bids have started to stack up on MPEx for these shares already. Of course, if the marketplace doesn't have the appetite for all the shares, then that's okay, for I'll just keep the shares and the revenue (it'll make the negotiations with the Macau gaming companies easier

).
Though, the Bitcoin investment world could do well with some "reasonable investments based on proven, transparent business models" as opposed to fleeting 7% per week shenanigans.
