Hello. I see that you've predicted that the $/btc will be less than $50 in two weeks. You seem like a very intelligent man. Would you like to make a small bet with me?
How about a large bet?

How much is large?
Would 20 btc each be large enough?
I'm in. Signed and sealed.
See you on April 12th.
We need escrow.
I can escrow these bets for you using
Casascius' escrow system as used in
this bet between mrb and micon if anyone's interested.
I doubt BitcoinTip is serious; he seems to just like the attention his words get him. But if anyone wants me to escrow a bet, I'll do it for free.
