Unlike traditional payment methods that can take several days to process, Ethereum transactions are typically completed within minutes. Additionally, using Ethereum for deposits allows for increased anonymity and privacy for users. Sportsbooks may also offer bonuses or incentives for using Ethereum as a deposit method, making it a more attractive option for bettors. Overall, offering Ethereum deposits provides a more modern and innovative approach to online sports betting.
