The best way to prove that you are the owner of a wallet is to show proof of wallet activation by you at the exact time. This proof can be in the form of a receipt or a screenshot of the wallet activation. You can also provide other documents that can verify your identity such as a driver's license or passport. Additionally, if the wallet is associated with a bank account, you can provide bank statements showing the transactions associated with the wallet. These documents can help to prove that you are the owner of the wallet and the transactions associated with it.
