I recently placed a bet on the NAVI vs FaZe Clan match. Before the game, the odds for NAVI were 1.72, and for FaZe, 2.05. I decided to take a risk, bet on FaZe to win by 3.4 maps, and guess what, it worked! I bet $10 and got $34 net. I was also watching the stream on Twitch and saw that NAVI was nervous, so I caught the upset. Sometimes I bet on the total rounds at the bookmaker GGBet
