The only tip that I'll be giving to you is just to know what game and the team you are betting in and surely you will earn tons of money.
I think that's definitely the best approach. My observations show that it's also worth following the profiles of all the players on the twitter of the teams we bet most often. It's also worth to follow the coaches and owners of organization. Often it is possible to deduce from the context itself what approach to the match the team will have. Of course there is not much of it but it will change.
It's also worth to keep an eye on the game changes. It is known that in the League of Legends, for example, the game changes a lot with each subsequent patch (new meta). Knowing the exact style of play of 1-2 teams in the league it is easy to bet if the new finish line is good for them or not. And especially at the beginning of the first matches the bettor has a lot of room for improvement. When the statistics are not important yet and we don't have results. Then the strongest weapon is what we have. That is to say, our own obstinacy and logical conclusions we can reach.
I've also noticed another tendency. Some of the odds are very unevenly divided favouring one team to the limit, which is a bookmakers' mistake and should be used. Bookmakers often set odds on the basis of popularity as the players play and those who often play only on the basis of their likes or completely amateurishly. The same is true of traditional football and other sports. Never play Liverpool with weakest team in preamier leauge per 1.12 or somethink like that
