Sure! Though I'd say just about any currency is fine to get started with. Keep in mind that you don't have to purchase an entire unit of a given currency - one Bitcoin may be $40k, but you can still just buy $10 worth (just be cautious of transfer fees, both withdrawing from exchanges and sending from your own wallet).

I'd recommend also looking at ETH (using MetaMask as an in-browser wallet to interact directly with websites is pretty cool) and XMR (dirt cheap transfers and your financial privacy is safe).
