We had a lad who bought a proper one of those for about £50 and turned up with it to our Sunday league game, within the first ten minutes it had been launched into a thorn bush and popped.
Looking through the thread on RAWK the general idea was to bet on singles at good value (around evens), it seems they had quite a few people who would look at the market and put forward the bet for that day and they would all then copy the bet. It was all about the value of the bet not looking for 1/4 favourites and just lumping on them each week.
I think it's supposed to be singles using the full winnings from the previous bet but you can do it anyway you want, I think the ideal is that in the end you have £1000 in your account from a number of single bets. I can't see a problem with only betting some of your winnings though and withdrawing some also.
There's a decent thread on RAWK about a £10 to £1000 challenge, just looked through the last few pages but one lad has managed to make around £500 and £300 in a week just betting singles with the £10 and winnings.
It's time to get rid, he's never going to get back to the heights of his first 6 months here or anywhere close to that. I'm sure there would be a buying in Germany or Turkey for him, I'd take anything around £5m.
