I put down the 18 hours stipulation for effect. I put this challenge down on Argentino when the conditions in Montana drove my daily win average up to $560 a day. That average took a dip to about $300 a day when certain games were removed but new games just out are driving my daily average back up again.
What was my chance of being successful with a bet like that against Argentino? It was 100% that I would do it. What you and Argentino don't know is I could easily set you up in such a bet and do it in less than an hour. It would more than likely have taken about 8 hours if I didn't want to set the idiot up.
And from what I can see your answer to the problem is to run a martingale. Voodoo gambling at it's best.
