FWIW, I can show on the blockchain that I only own about 1.1BTC and that most of that came from Dragon's Tale casino and sealswithclubs.
You could always own another 20 BTC in an address you wouldn't reveal.
Sure I guess that's true. However, I'd really like for tradefortress to show *me* the addresses that he ostensibly sent 1.5 BTC to. That's real missing piece here. A guy shows up and says he "risked 1.5BTC" on me but isn't around to reply to questions like "huh?" "what?" "when?" "where?".
