You have to be smart enough and analyze correctly when choosing each bet that will be included in the multibet because one is enough to ruin everything. If I'm not mistaken in one of the threads of sports betting there are people who won $1,000 just by betting $1 at a total of 1,000 odds on the bet, it's not easy for you but if you can do it you will also be surprised at first why it happened
Thats a very nice win offcourse and I think we all dream about that, but winning a bet with these odds is just pure luck. It is always to place bets like that as there is a very small chance to win bets like that but I dont think that in the long end, you will end up in profit if you keep placing bets like this.
