How to earn free Crypto on Coinpoker?

I've been hearing about the opportunity to earn free cryptocurrency on Coinpoker, but I'm not entirely sure how it works. Could you explain in simple terms how users can actually accrue crypto without investing upfront? Are there specific tasks or activities I need to complete, or is it a matter of playing poker games and earning rewards? I'm also curious if there are any limitations or requirements I should be aware of before I dive into this. I'd appreciate a concise yet comprehensive overview of the process and any associated nuances.
