So many early adopters have similar tales of using Bitcoin for gaming or small purchases back when it seemed like "internet funny money." The important thing is you're here now and learning.
Don't let regret consume you though. Yes, those early Bitcoin might be worth a fortune today, but remember that nobody could have predicted this trajectory with certainty. Even if you had held onto them, there's no guarantee you wouldn't have sold during the 2017 peak or any other major event.

The real value is the lesson learned. You now understand Bitcoin's potential and the importance of long term thinking in crypto. Many people are still completely unaware or dismissive of Bitcoin even today. Focus on applying this knowledge moving forward rather than dwelling on the past.
