1. Either the member needs to sign a bitcoin message to show that he/she is an IPO investor (to prove that he/she is the owner of a bitcoin address for IPO investment).
2. Send the qora address to dev and be verified by the dev?
1. Doesn't prove. Stake could be sold by now.
How about sending 1 coin from the address someone claims belongs to him?
Good plan. But there is only one problem -- What if a person's qora asset does not reside in one account? So we ask the person to send 1 qora from each account he/she owns?
That sounds fine. I like your idea
Yep. He could just send 1 coins from an address with say 35M coins and 1 coin from an address with 15M.
