The chances of winning a crazy bet is very rere but the odds are very big compared to normal bets, but when you are lucky it pays very big. However sometimes gambler need to bet on crazy bets because we even lose the normal bets. So sometimes it's better to take the chance an hope to get lucky. However before doing that, must risk with what can be afforded to lose. A gambler that bets on a crazy bet shouldn't wager big money because it's very hard to be lucky on crazy bets.
But the crazy and small odds are still high risk because you can lose in either of them as you do not know which team is going to win but the chances of losing in small odds are small compared to the chances of losing with bigger odds. You can decide to gamble on the big odds and if you win, you win life changing money but do not put too much hopes on the big odds because the criteria for those odds are very hard to get. Usually when underdogs are playing against other bigger clubs, the odds for the underdogs are always bigger but for them to win is almost impossible although there are some games that the underdog will win and for those that took the bigger odds, they will win.
