Key takeaways
- Bitcoin's seven-day active supply hit a 2026 high of approximately 890,000 BTC moved in a single seven-day span, according to K33 Research.
- The activity spike coincided with the Coldcard hardware wallet attack, which K33 described as "panic visible onchain."
- K33 simultaneously flagged a potential bottoming pattern taking shape in $BTC but stopped short of a directional call or confirming a floor.
- The 890,000 BTC figure is a year-to-date record for weekly active supply, per K33.
- Whether the flow was defensive or distressed remains unclear, making the bottoming setup conditional and unconfirmed.
Bitcoin's seven-day active supply reached a 2026 high this week amid the Coldcard hardware wallet attack, with K33 Research recording approximately 890,000 BTC moved across the network in a single seven-day span. K33 described the reading as "panic visible onchain" and, in the same report, flagged a potential bottoming pattern taking shape in $BTC.
The onchain print
The 890,000 BTC figure is a year-to-date record for weekly active supply, per K33. Seven-day active supply counts coins that have moved at least once within the rolling window, making it one of the more direct reads on whether holders are acting or sitting still. At a 2026 high, the print says holders were clearly acting.
A security event driving volume of this scale matters for how you interpret the signal. Panic-driven flows and orderly repositioning look similar in aggregate onchain data. K33 is flagging both the distress and a constructive pattern simultaneously, which means the setup carries conditionality.
K33's bottoming signal
K33 paired the activity spike with an observation that conditions are consistent with a potential bottoming pattern in $BTC. The firm stopped short of a directional call. Potential is the operative word: K33 is noting a setup, not confirming a floor. That distinction is worth holding as the Coldcard situation remains unresolved.
For a derivatives desk, the natural follow-on question is whether elevated onchain activity is registering in open interest or funding rates. The source does not provide those figures. The onchain data establishes that a significant volume of Bitcoin changed hands. Whether that flow was defensive or distressed is the read that determines how durable the setup is.
What to watch
The Coldcard attack is the active variable. Its scope and any further disclosures from affected parties will determine whether the 890,000 BTC weekly print was a single-week event or the opening of a sustained period of elevated flow. K33's bottoming pattern is the setup to monitor for confirmation or failure in the sessions ahead.
