Solutions to above possibilities,
1. No solution
2. Sign a message from BTC address 1DAXoynA9hMQ1fY6nPeBCA2YnmLjptaaev or DOGE address DM6XDBtWNrDHmywfHfuJ6XYn9eoPwcfvSf to prove ownership of account
3. 20,500 will be sent to desired address
That is an old multibit wallet that I haven't used in years, but I'm sure I can figure out how to sign a message.
My reasoning for wanting to keep hidden isn't for a $105 dispute, it's the fact that more info can be gained from that transaction, like my full wallet size. Do you post your exact holdings on a public board? Maybe no one else cares about stuff like that but my financial business is no one elses business.
edit- alright message sent
