Onchain data is highlighting critical support levels for bitcoin, with the 2023 investor cost basis serving as a key anchor and a broader historical floor near $54,000.

Bitcoin recently rebounded from its 2023 realized price—an indicator representing the average purchase price of coins acquired that year—currently around $63,700. During the early February sell-off, when bitcoin dropped roughly 50% from its October peak to near $60,000, the asset tested this level and held, reinforcing it as an important support zone.

This behavior reflects patterns seen in the previous cycle. Throughout 2023, as the bull market developed, bitcoin experienced multiple pullbacks and consistently found support at its realized price. Similar consolidation phases occurred in March, July, and September, when prices traded in the $20,000–$26,000 range.

Newer investor cohorts are now facing pressure. The 2026 realized price started the year near $90,000 but has since declined to around $77,000. With bitcoin currently trading just above $70,000, these holders are underwater. Their cost basis has also dropped below that of 2024 investors at $81,500 and 2025 investors at $96,400.

Looking at the broader picture, bitcoin’s aggregate realized price—representing the average cost basis of all circulating coins—stands at approximately $54,360. Historically, bitcoin has traded below this level during every major bear market, including 2011, 2015, 2019, and 2022.

So far in this cycle, bitcoin’s lowest level has been around $60,000. If that support breaks, it becomes a critical downside threshold, with the aggregate realized price near $54,000 acting as the next major level to watch.
