What would make a finance government unit suspect that a screenshot of mt gox showing bitcoin from several years ago is a fake? Someone was using it to corroborate their source of funds to buy a house and brand new car? What would tip off law enforcement if they were faking this?
Mt. Gox Bitcoin ownership screenshots may raise red flags because, in the real sense, they do not show verifiable trace evidence of funds, such as transaction history or records on the blockchain. However, with Mt. Gox collapsing in 2014 and with disputes between creditors still ongoing, law enforcement and financial units will likely investigate such claims as suspicious should they fail to follow Anti Money Laundering standards. Particular suspicions regarding fake screenshots arise if timestamps, account format, or metadata do not match patterns in the historic record.
The use of such unverified statements for significant transactions, such as buying a house or an automobile, could amount to suspected fraud or money laundering. All financial institutions require explicit, auditable confirmation of the source of funds, and any deviation from the norm might invite litigation. Without believable testimony to the contrary, any attempts at authentication of title with old or phony information will likely not survive scrutiny.
