Two more questions

(3) Concerning escrow for IPO, why escrow with bitcoin multisig is not used?
P.S. It is more safe and protecting IPO investors using a multisig bitcoin address for payment (those btc address starting with "3").

(4) Is your company a registered company? If yes, please provide the registration information and the proof (e.g. location of registered and official registered number)
P.S. Only a registered company can do real "merchant" business.
