When you eventually do though, for privacy reasons, you may want to consider signing from an address you are not going to use to send/receive bitcoins on. I’ve seen lots of addresses in the stake thread that have a balance and history of TXs, and I’m pretty sure that it’s better to avoid that.
Your initial priorities should likely reside in reading on bitcoin itself, determining how to obtain it, how to perform self-custody, deciding on the wallet to use, determining the entailed safety measures and so forth.
