How do I buy cryptocurrency on Skrill?

Could you elaborate on the process of purchasing cryptocurrency through Skrill? As a potential investor, I'm interested in understanding the steps involved. Do I need to have a pre-existing Skrill account? Are there any specific fees or charges associated with the transaction? Also, how secure is the platform for conducting such transactions? Furthermore, does Skrill support a wide range of cryptocurrencies, or are there certain limitations? I'd appreciate a concise yet thorough explanation of the entire process from start to finish.
