The most frequent influence on me in betting ends badly is the analysis of betting odds. especially a very strong team match even on paper will definitely win. Odds are definitely smaller but that allows us to bet multi with similar Odds options. not enough with that, usually the biggest mistake is to raise the bet. the results are in accordance with predictions, but for some reason, there will always be unexpected matches.
At times like that, then we must really believe that gambling always relies on luck.
It often happens that you are too confident with the odds that are bet small {strong team vs low team} at the most odds that have 1.20 that still lose because of unexpected matches.
I've seen someone lose a huge amount with odds of 1.09, imagine it should be a win on paper right?
Sports betting analysis is still needed, luck also depends on it, so for me the worst system is with low odds still losing.
