Been looking at Bitcoin's december 31 closing prices over the years and it's wild to see how much the bitcoin price has evolved. Just saw that BTC closed 2025 at $87,934 on New Year's Eve, which is pretty interesting considering where we were just a few years back. If you go back and check the historical data, you can see the whole journey - started at basically nothing in 2010, then $4.74 in 2011, jumped to $757 by 2013. Fast forward to 2021 and we hit $46k on the last day of the year. Last year's december 31 close was $42,320, so we've seen some solid movement since then. The volatility is real though - remember 2022 when it dropped to $16,554? That's what makes tracking these year-end levels so important for understanding where we've been and where sentiment was at those specific moments. Pretty cool to see the long-term bitcoin price trajectory when you lay it all out like this.
