Town would get 10% over the 4 trillion, so 400 Billion (should have stipulated this--and no, this would not affect the Bounty total). This is needed to create Bounties--like the one you'll receive--so necessary if you want to jump start development.
Will people want to trade the ownership token? I'm happy either way and would be fine with it being an ownership token, just feel the question should be asked.
Also, Risto's shares would go to whom? I would be happy if Mooo as GM would hold them until the obligation is met or the funds could be used to pay back creditors.
You don't seem to understand my question.
If there is 4 trillion M and we will not issue more M, it is all currently owned by users ingame, how do we create the 10% with the supply remaining the same? It makes no sense

What does make sense, is that Town holdings remain town holdings and that Ristos holdings get transfered to Town in order to liquidate his debt and the issue of bounties etc. is resolved.
A CK ICO of Ristos holdings is also a viable option.
