A deposit bonus in the crypto world is an incentive offered by exchanges or platforms to attract new users or encourage existing ones to deposit funds. Typically, this bonus comes in the form of additional cryptocurrency credited to a user's account, based on the amount deposited. For example, a platform might offer a 50% bonus on the first deposit, allowing users to trade with more capital. While deposit bonuses can enhance trading opportunities, it's essential to read the terms and conditions, as they often come with specific wagering requirements or withdrawal restrictions.
