people who bet small odd with huge amount of money is people who has experience in gambling, and in their mind they has made a decision neither they win or they lose, I don't bet so many bets, my bet always be on minimal games or few games but I will use higher amount to stake it, hoping that anything can happen, if I'm opportune to win, but i do bet with big amount, because the amount I used to bet will determine the potential wining...but some people stake small amount of money with long numbers of games, and at end maybe one or two games might cut it, so it's better for you stake your bet with few games with big amount, and concentrate on the odd before we stake, it's necessary because the odd will determine the amount you will place on bet.
If the amount are such that you can comfortably afford to loose without having to think about it or get emotional then it's a good choice otherwise I will advise you don't use big money except you have been able to groom your account to the point where you can now be able to stake risk free, more like your stake are the profits you have made much earlier so you don't even have to stress about it even if you loose it at any point.
Sometimes many people will not ready with their losses because that is out of their expectation. They believe that will win in that match but they lose in the end of the match and they can not believe that and not accept their lose. That is why they must always know that playing gambling can make them lose their money so they must know how to prevent the big lose. If they cannot accept the lose, they must forget about placing their bet and never visit any casino because that will just give them a problem. If they can hold themselves from the wanting to placing their bet, they will not feel sad to see their money is lose because they can use that money for buying other things.
