Betting itself is fairly simple. Let's say that an esports match for CS: GO has just started between Team Liquid and Fnatic. You think a particular team has a higher chance of winning this match. To bet on it, you place a wager on that specific outcome. If you win the bet, you get some money in return. However, if you lose it, you get nothing.
This is just a simple explanation of how csgo betting works. What amount you will get in return if you win the bet and what are the exact chances of a team winning a match or any other outcome occurring are not straightforward questions. Both of them depend on a betting term called odds, which in this case is CSGO odds.
While there are a lot more esports betting terms that you need to understand about bet csgo before you get into it, betting odds are probably the most important one. If you have a solid grip on CS: GO betting odds, you can safely start betting on CSGO events with a relatively higher success rate.
