How do I sell my Splinterlands cards?

I'm curious to know, could you elaborate on the process of selling Splinterlands cards? As a crypto enthusiast, I'm looking to offload some of my assets, and I've heard good things about the potential market for these digital collectibles. Is there a specific platform or marketplace where they're typically traded? Do I need to consider any specific factors when determining the asking price? Lastly, are there any safety precautions I should take to ensure a smooth and secure transaction? Thank you for your insight.
