Is there anyone who gambles without doing their proper analysis?
Of course we all need time to properly predict and review our games to place us in a higher chance of winning, we can't just rely on the fact that we knows the teams proper hence we could just place our bet and expect to have winning. It doesn't work like that we must thoroughly go through our games before finally place bet.
Ideally we must do deep analysis but there should be some people who are lazy to do it. Making a proper analysis must take a lo of time and it requires efforts. Some people don't have time to do it, they want to gamble with almost no effort. So, they prefer to guess over doing proper analysis to have a better bet. Some people also think that doing a proper analysis doesn't guarantee the win, so they assume to rely on the luck only. They just place their bets on the team that seems to have a better chance to win.
If someone does not know about a league yet place a bet for a team, that's a dumb thing. A gambler has a lot more options on the market. The casino market is huge and there are thousands of casinos where a player can gamble. I do not see any reason why a person would place a bet on a league that he does not know anything about.
Indeed. People probably bet on the league and the teams they know well. They have no reasons to bet on unfamiliar leagues, it is just something impossible. For example I don't know MLS and the football teams there, so I have no intention to bet on MLS matches. It makes sense because I have no idea to bet on MLS matches. I prefer to bet on familiar leagues such as EPL, La Liga, Serie A, or Bundesliga.
