Betting on esports is a relatively new phenomenon, but many people have won large sums of money by wagering on games ranging from Dota 2 and League of Legends to CS:GO and Valorant. An eSports betting site promotion code, also known as a promo code, is a code made up of letters or digits that players can type into a promotional box on a betting site to receive some sort of special incentive. A bookmaker promo code is generally used by bookmakers as an acquisition strategy to help attract new customers and can assist you in getting started with eSports betting.
