BITCOIN ACTIVITY HITS 2026 HIGH AMID COLDCARD ATTACK AS K33 FLAGS POTENTIAL BOTTOMING PATTERN

Summary from the TLDR Crypto newsletter

K33 says roughly 890,000 BTC moved onchain over the past week, the highest seven-day active supply of 2026, coinciding with the expanding Coldcard exploit, which Galaxy Research now estimates involves at least 15 attackers and roughly $130 million (~2,000 BTC) in losses. K33's Vetle Lunde said such spikes in active supply have historically coincided with local market tops and bottoms, arguing "panic is visible onchain" as holders react to hardware wallet security concerns and price declines.
