Playing online or offline gambling which is more preferable in terms of risk reduction?
I don't know if there is a right or wrong, safer or more risky... my opinion is that it depends a lot on the player's profile.
There are players who like to plan everything in advance, they research the teams calmly, study the lineups and probabilities of each result a lot and only then make their bet sets and take them to the end, no matter what happens, they don't change their bets. betting strategy because they feel confident in the choice they made... they are extremely strategic people.
On the other side, there are those who like to play with emotion, they only bet when the game is already underway because they believe that the outcome of a match is defined based on the current events of the game. These people don't believe in mathematics, they play with the unpredictable and bet on the result that seems to be most favorable at that exact moment.
In other words... trying to invert the type of bet between these two players will cause a "tragedy" on either side, the most favorable betting scenario varies greatly according to the bettor's profile and consequently the risks and gains follow this personality.
