How can I prove ownership of hardware wallet? I’m applying for a mortgage loan and I recently made a large deposit into my bank account from crypto stored on a ledger hardware wallet .  I sent the funds to Coinbase where I converted to usd and withdrew into my bank account.
The mortgage lender is giving me trouble about providing proper documentation. I mined most of it a few years ago so I don’t have a record of purchase.
Is there anyway that I can provide proof that I own the original source wallet?
What you need to do is find some document that associates you with the virtual or hardware wallet. The most obvious way is the receipt you used to purchase the physical wallet. If you didn't keep the receipt, the company you bought it from may be willing and able to help you.
