Esports betting site. It specializes completely in the world's most popular cybersports and features betting, live, and news sections. Every newly registered user gets a double-deposit bonus of up to $600 with the first deposit made on the platform. There are several ways to deposit money on your account including Bitcoin and other popular cryptocurrencies.
