Wie funktioniert ein Bitcoin-Bonus?

Could you please explain in detail how a Bitcoin bonus works? I'm curious about the process from start to finish. For instance, how do you typically earn such a bonus? Are there any specific requirements or conditions that need to be met? And how does the bonus get credited to my account? Additionally, are there any restrictions or limitations on how I can use the Bitcoin bonus once I've received it? Lastly, are there any risks associated with accepting a Bitcoin bonus, and what steps should I take to ensure my safety?
