That is what called by live betting, we make the bet while the game is running.
The risk does exist regardless when you place the bet, both before the match start or while the match running.
I do live betting some time especially in a match where it is hard to predict.
You can get better option to bet by watching the game for several minutes, of course it is all about preferences.
Obviously, it was better to bet with odds of 2.9 than with odds of 1.9. I understand the strategy when the bettor is waiting for a situation when the favorite falls into the lagging position (at this moment the coefficient for its victory grows) and makes a bet, but I don’t really like the strategy of waiting for the favorite to come out ahead (the coefficient for its victory falls) and at that moment do bet.
