When you sign up for an account at a betting site for Dota 2 you are entitled to expect generous bonuses. Unikrn will match your first deposit by 300% up to $450, which is one of the best offers currently available. GG.bet also has a €200 deposit offer for new customers, while LuckBox will simply double your first deposit up to €100. The size of the bonus is obviously important, but when you try to figure out the best possible offer, it is important to choose one with reasonable wagering requirements.
