UPDATED STATS (Aug 24)

When the IPO was announced about 6 days ago, the P/E ratio was 10x.  Some people said that was too high of a valuation and we've been debating this as is proper.

I updated the stats today to reflect the past week of numbers, as well as added a new metric showing P/E based on past 30 days (not based on all time performance).

https://docs.google.com/spreadsheet/ccc?key=0Aiec3-Eo_yO5dG5SQklHZG4wRm1GMW9DRWpMMW5UQkE#gid=0

Current P/E based on all-time performance:  8.79x
Current P/E based on past 30 days performance:  4.72x

Thus, if SatoshiDICE remains flat from here, and neither grows nor shrinks in usage from actual past 30 days' performance, it's priced at a 4.72x multiple. Annual dividend yield of IPO prices is 21.20%

I can't stress enough that all these numbers are based on actual real-life performance, they are not wild-eyed estimates of possible future growth figures, etc. I think it will be hard to continue to argue that this asset is priced unreasonably.
