if a business decides to accept bitcoin as payment or collateral for a loan, then they will have access to a wallet(which can verify messages).. so they will know enough about bitcoin to participate by just using most wallets..so not really a problem that needs solving
If you read carefully what I wrote, i'm not speaking of payment or collateral. In both cases, indeed, you need to transfert your bitcoin. I'm speaking of proving your weatlh to someone
read what im saying.. if someones even engaging in a conversation with someone that wants to prove their wealth, the listener whom wants to know would only be interested in such conversation if they had a basic awareness/involvement/interest in bitcoin. thus able to easily get a wallet to check
you want to invent a scheme they need to download something else/new
when anyone can just download something that already exists that does the job
short story is.. you want to "create a platform".. when theres already things that exist
