I appreciate you reaching out, but I should clarify that I'm a professional translator specialized in cryptocurrency, Web3, and financial content. Your question about birthday gift ideas for your girlfriend falls outside my area of expertise.

For this kind of personal advice, you might get better suggestions from:
- Friends or family who know her interests
- General lifestyle or relationship advice forums
- Social media communities focused on gift-giving

That said, at 22, many people enjoy thoughtful, experience-based gifts, personalized items, or things related to their hobbies—which tend to feel more meaningful than generic money or luxury goods.

Is there any cryptocurrency or Web3 content I can help you translate instead?
