It`s money management. If you want not only to play for process, for emotions but win - you must have strategy and follow it. Here we just see one big lose but we don`t see the full result. May be he made more than 1000 success bets with such odds and it means that his strategy is ok. I`ve seen how guys tried to catch odd 100 and i saw how they won.
As for me - i prefer make the same bet for all matches i analyzed and it depends on my "bank" - the sum i use for gambling. There are some other details, but it is just an example of strategy.
Making more than 1000 successful bets doesn't sound plausible even with such small odds. At least for me, a strategy with such low odds was almost always ineffective, as losses occurred much more often than expected. For example, 2 losses per 100 bets with such odds were not uncommon in my case.
There are two things that make lose find place in ones bet, one is of the odds are like 1.01, the gambler will not be satisfied with the potential amount no matter how much he used to stake on the games, which means that the gambler will need to add more games for the odds to increase up to 1.50 or 2 odds if possible. And the more games you add the more loss finds place on the games.
Two is that if the odd is very big loss can also be closer to the games because most big odds are like a trap set for a gambler. But the truth remains that a gambler needs luck to win his bet.
It is your point of view. But it doesn`t mean that all other gamblers think the same. I don`t want to say that you is mistaken, but there are different strategies.
I saw how gamblers won with the odd 100, but they bet from $20 to $100. Here we see how someone bet big money to get small but stable profit. Here he mistakes but we can`t say that he lost all his money or that his strategy is bad - we just don`t have enough information.
