Speaking of researching before betting, I always did very badly in my research. It's strange that I was supposed to do research and be successful. But it turns out that in the past I researched on YouTube about how to analyze football games, I followed all the steps, but I lost a lot. I compared following those steps with what my experience told me, I realized that it was better to continue with my experience
For game that depend on luck, I also made the same mistake, I searched on YouTube how to be successful in plinko and the guy on YouTube said to do martigale, I tried it and lost, I stopped playing plinko and all games that depend on luck.
Research cannot help you win, it can help you take the right steps and increase your chances of winning. For example, you are a football expert and you have been researching football for many years. Can you tell me who will win the match between Real Madrid and Atletico Madrid? Or who will win the match between Barcelona and Leganes?
You might say in the first question that the match will be competitive, both teams are favourites to win. But in the second question, you would definitely say that Barcelona will win the match. But Barcelona lost to them in a La Liga match. Here your research is completely useless and the outcome of the match depends on luck. So research cannot guarantee you to win the bet but it can increase your chances of winning a little.
