I do not discuss that with you. I just said, the funds in bitcoins are there and I do not want to sign any message, because then the private key and also the password leaves the safe place. And I just said, that we will buy another coins if the coins does not suffice.

Do not understand your problem... You can see there 1,500 € (1,656 US dollar), this is a standard amount in my wallet. Also, you can see there a key for a car which is about 130k € worth. If you do not trust me, just do not play on my site. If I would sign a message, who says you that we will withdrawal the funds? That is the same thing with the fiat money. You have to trust us. If we say we have enough coins or we have enough fiat - or even both -, the thing is not to have it but to cash it out to winners. We cash it out. But this you can only judge if you try it.
