Coldcard Exploiter Moves 45% of Wave 3 Loot as Stolen Bitcoin Enters CoinJoins

The immediate market impact is bearish at the headline level but limited in direct supply terms. The key issue is not that 45% of Wave 3 funds have moved, but that the attacker is actively converting previously dormant Bitcoin into potentially spendable liquidity. Funds routed through THORChain to Ethereum and into CoinJoins are harder to monitor, increasing uncertainty over where and when selling could occur.

For BTCUSD, this creates a short-term overhang rather than evidence of an imminent large market sale. Across all attack waves, approximately 82% of the stolen coins reportedly remain in attacker-controlled addresses, meaning the larger liquidation risk is still contingent on future transfers. The systematic movement of the largest vaults first is relevant because it could concentrate any eventual selling into relatively large transaction batches rather than producing a steady, evenly distributed flow.

The most bearish scenario would be a subsequent transfer to centralized exchanges, brokers, or identifiable OTC counterparties. That would raise expectations of realized selling pressure and could amplify downside if it coincides with weak liquidity or broader crypto risk reduction. By contrast, CoinJoin activity alone does not establish that coins have been sold; it primarily signals efforts to obscure provenance and may delay the market’s ability to identify liquidation venues.

The broader implication is reputational: the exploit involved a weakness that materially reduced the security of some older Coldcard devices, potentially reinforcing concerns about hardware-wallet reliability and self-custody. That could weigh more heavily on affected-wallet users and related infrastructure providers than on Bitcoin’s fundamental demand, particularly because the reported incident previously produced little observable price damage.

Trading relevance:

the event is likely to remain a volatility and sentiment catalyst, with the directional impact dependent on blockchain evidence rather than the headline alone. Traders should monitor whether the remaining 82% begins moving, whether funds reach exchange-linked addresses, the size and timing of confirmed BTC disposals, and whether the exploit prompts wallet recalls, compensation measures, or broader security concerns. Without confirmation of exchange deposits or actual sales, the appropriate interpretation remains cautiously bearish but uncertain, rather than a standalone market-wide sell signal.
