Bitcoin's onchain activity has surged to levels not seen this year, with nearly 890,000 BTC changing hands over the past week. The spike comes amid a reported attack on hardware wallet maker Coldcard, and analysts at K33 Research suggest the market may be forming a bottom.

Onchain Metrics Hit Annual High

According to data from K33 Research, Bitcoin's seven-day active supply reached a 2026 high, with about 890,000 BTC moved on-chain over the last week. This level of activity is often seen during periods of heightened volatility or major market events, and the recent Coldcard incident appears to have been a catalyst.

The term "panic visible onchain" was used by K33 analysts to describe the flurry of transactions, as investors react to security concerns and market uncertainty. Such spikes in active supply can indicate that long-dormant coins are being moved, potentially signaling a shift in sentiment.

Coldcard Attack Adds Fuel to the Fire

Coldcard, a popular hardware wallet known for its focus on security, has been the subject of an attack that has rattled the crypto community. While details remain scarce, the incident has prompted many users to transfer funds, contributing to the elevated onchain metrics.

Hardware wallets are generally considered one of the safest ways to store cryptocurrency, so an attack on a leading brand can have outsized psychological effects. The movement of nearly a million BTC in a week suggests that both retail and institutional players are taking action, whether to secure assets or to trade the volatility.

What Does This Mean for Bitcoin's Price?

K33 Research has flagged that such spikes in active supply have historically been associated with market bottoms. When panic selling occurs and coins move in large volumes, it can mark a capitulation event, after which prices often stabilize or rebound.

However, analysts caution that this is not a guaranteed signal, and the market remains highly uncertain. The combination of a security scare and broader macroeconomic factors could lead to further downside before any sustained recovery.

Market Sentiment and Historical Context

Looking back at previous cycles, similar onchain activity surges have occurred during major sell-offs and crashes. For example, in 2022, a spike in active supply preceded a period of consolidation before a eventual recovery. If history rhymes, the current movement could be a sign that the worst is behind us.

Yet, the crypto market is notoriously unpredictable, and external shocks—such as regulatory news or further security breaches—can quickly change the narrative. Investors are advised to keep a close eye on onchain data, as it often provides early clues about market direction.

Key Indicators to Watch

  • Active Supply: The number of unique coins moving on-chain. A sustained high level could indicate continued distribution or accumulation.
  • Exchange Flows: Large inflows to exchanges often precede selling pressure, while outflows suggest accumulation.
  • Whale Activity: Transactions involving large amounts of BTC can signal institutional moves.
  • Network Hashrate: A stable or rising hashrate indicates miner confidence, which can support price.

What's Next for Bitcoin?

The coming weeks will be crucial as the market digests the impact of the Coldcard attack and the surge in onchain activity. If the bottoming pattern holds, we could see a gradual recovery, but investors should remain vigilant.

K33's analysis suggests that the market may be reaching a point of maximum fear, which historically has been a contrarian buying opportunity. However, timing the bottom is notoriously difficult, and many prefer to dollar-cost average into positions during volatile periods.

Key Takeaways

  • Bitcoin's seven-day active supply hit a 2026 high, with ~890,000 BTC moved, according to K33.
  • The spike is linked to the Coldcard attack, prompting onchain "panic" activity.
  • K33 flags this as a potential bottoming signal, though caution remains warranted.
  • Investors should monitor onchain metrics like active supply, exchange flows, and whale activity for further clues.
