Start watching CS:GO or Dota 2 games and tournaments and make bets. It is not hard really. I would like to say that it is easier to earn with Esport betting than with soccer betting for example. After 5 years of betting for Soccer and making some bets for eSport games, I realized that it can make some income to my budget. Just watch the games, play them on your own sometimes to understand the algorithm and use this site or others to see predictions for upcoming matches and result s of previous as well as comparing the statistics of some teams.
