The first time I got to know with sports gambling I was stuck in simulated reality games and placed bet almost 50$ seeing the odds given biggers, but it felt strange when I checked the flashcore site there were no football matches displayed there and realized that it was only simulated reality games. This should not be displayed on sports betting sites because it can be a trap, especially for beginners.
I made the same mistake once! I saw familiar teams playing and I placed a bet, only after placing a bet it came to my brain "it was not the right time for that (it was in the morning hours), and then I realized that I placed a bet on some simulated reality game! Well, since then I pay more attention, and I guess you are right that beginners often make this kind of mistake, at least once!
By the way, except LoL, I don't follow and bet on anything else connected with esports! I still like "the old way", betting on real sports, more attractive!
