I know some people that do gamble on legs which they no knowledge about, what some of those people do is make use of the statistics which they see to make prediction, and sometimes they are always right, but also sometimes they are wrong.
I don’t really bet on sport or team which I have no knowledge about, whenever I decide to do that, things are not always working out for me, so I just focus on sport which I know I have proper knowledge about, and teams which I know have been following their matches for some time, and I know what they are capable of.
Yeah, that is right because we don't know anything with the team so we could only guess which can lead us losses the money. It is better we place on the team that we know and have a chance to beat the other team. But we could only know if we analyze each team even if we know both teams because with analyze the team, we will have more information about both teams so we can pick the right team that have potential to win.
We can not risk our money to pick the team that we don't know because that will reduce our percentage of win the match. Although we will not guarantee to win but we have the information that we know which team can win.
