How about a physical cryptocurrency wallet? These wallets are designed to store cryptocurrencies offline, providing an extra layer of security for your girlfriend's digital assets. You can find a variety of options online, from sleek, compact designs to larger, more decorative models. In addition to being a functional gift, this would show that you appreciate her interests and support her hobbies. To make it more personal, you could even consider engraving a special message or her initials on the wallet.
Or you can get her a star map with the date of your first kiss.
