As far as I know you can prove you received or send it () but don’t know how to prove you have (not had) some monero. It might not be possible, definitely not in a bitcoin way. I guess you should move the funds to a new wallet on the last block and share the pub key right away. Or maybe some multisig way? I kind of like it. It makes it “unETFable”

Interesting. We will see about that :) someone would just do an monero etf and tell people to believe it and enough buyers will be found :)) same type of btc etf buyers… they know better, but do it anyway 😅
Everybody gets what they deserve
