The bank seems interesting, but why should I buy shares for the alliance? Sure, I want bitcoin to succeed, but having 2500 shares within the alliance... what does this arbitrary number mean? Can I vote for things or so?
The alliance share offering is basically a donation... In order to boost bitcoin popularity.
Ah.. just what I thought.
You could however turn it into an organisation that also does lobbying and that kind of stuff. With the shares having a way to submit ideas and votes on proposed actions with all the shareholders.
