For a safer gambling idea, split it into a number of bets on different sports matches that are all really shit odds (like 1-3 odds), you've got a decent change that they'll all win, and if they don't you'll almost certainly still have some left (if not more than you started) because you split it. Repeat until you hit the magic number.
There is zero advantage to making several bets at the same time. So really what your suggesting is to make a series of bet's until you reach your desired goal. Unfortunately with most bet's the expected value is less than 1 so the more bets you make the higher your expected losses.
