Hello there, I'm interested in purchasing some cryptocurrency using ShapeShift, but I'm not entirely sure how to go about it. Could you please walk me through the process step-by-step? Specifically, I'd like to know what kind of information I need to provide, what types of cryptocurrencies are available for purchase, and whether there are any fees associated with the transaction. Additionally, I'm curious about the security measures in place to protect my personal information and funds. Any guidance you can provide would be greatly appreciated.
