If you're thinking about punting on the financial markets then take a leaf out of Toth Kalman's book, and hope it's not in Hungarian. The Eastern European gambler had taken the bookies for £200,000 ($366,360) cash betting through betonmarkets.com.

Kalmon specializes in fixed-odds financial bets, concentrating on equity indices in Frankfurt, New York and London. His strategy is to follow trends and then to bet on whether an exchange will rise or fall over a given period. Kalmon would make relatively large individual bets, over £1000 ($1831.80) with wins and losses of over £8000 ($14,654.40).

Kalmon is planning on creating a website based on his financial betting expertise, something to keep an eye open for if this area of gambling interests you.
