You've got some great replies and some really good questions I see. I'll reinforce what some people have been saying. Definitely get a hardware wallet. I like the Coldcard from CoinKite. Avoid the Ledger hardware wallet. It's okay if you use Coinbase as an exchange for a while. I recommend eventually using Strike instead of Coinbase. Take it all slow & learn the basics of on-chain Bitcoin. There's also a lot of leveling up you can do beyond hardware wallets! 😄
