When it comes to the Internet, verification for credibility always becomes a problem and a lot of persons get away with lies. Though, in exact seems to agree in both threads and that is; the available finance to operate with but that too is a claim.
A signed message on an address with such amount as stated by LoyceV could stand as proof and offer some credibility to the story but, I don't think OP could do that having no computer coding knowledge.
