What I found more interesting was that he wasn't worth anything like he thought he was. At the beginning of the program he thought he could get £150k together but after he sold everything he only had £55k (£25k of that was a share in his dad's company). BlueSquare.com gave him another £20k if he would change his name to Ashley BlueSquare!
Anyway, I can't really see what he would gain out of what he did even though he won. He still has to buy back all the stuff he sold. I think he got £25 for his video recorder, a new one will cost him at least £50 so it's a good job he doubled his money!
What was interesting, from a trading perspective, was that none of the casino's wanted to take the bet. Roulette has negative expectancy so from a punters point of view the longer you play the more likely you are to come out losing. Ideally, therefore, you want to risk the lot on one spin - that way it really is a pure gamble and you could actually end up winning. If you sat and played roulette for hours and hours risking 1% at a time over thousands of spins you are pretty much guaranteed to end up with less than you started with, as the negative expectancy kicks in - much better to gamble the lot on one spin. The casino's want you to sit there for hours so that the house edge has time to work for them.
