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?
