Is there a buyback/contract change policy?
yes, see OP -- Both Nyancat Financial and CPA will jointly maintain a bid wall near the NAV.
No, I meant a case of forced buyback, or is a forced buyback simply impossible?
Also how does Nyancat Financial get money in the first place?
Please tell me if the following is correct:
NYAN tries to have a ~balanced amount of NYAN.A B and C shares
NYAN sells these shares for 1 BTC each to CPA (<-- I'm not sure about this one)
CPA then sells these shares on the market at IPO time
In this case, NYAN can have money, if CPA just gets the shares without payment, where should the money in the NYAN account come from? All earnings from NYAN activities are paid to NYAN.X shares again...
