$89M Bitcoin Security Breach Exposes Coldcard Flaw, Adding to Crypto Woes
MSTR sits 16% above its 52-week low of $81.81 on light trading volume (0.2× avg).
Summary
A weekend exploit drained over 1,000 Bitcoin—worth roughly $89 million—from 1,196 wallets, traced to a coding error in Coldcard hardware wallet software. This is a systemic risk event for Bitcoin infrastructure, not a Strategy-specific hack, but it directly threatens the asset that underpins Strategy's $53 billion Bitcoin treasury. The breach compounds an already fragile crypto environment: Bitcoin is down over 20% in 2026, and Strategy just disclosed selling 1,638 BTC for $105 million, at ~$63,957 each, to fund preferred dividends and buybacks. The sale itself was previously reported, but the Coldcard vulnerability is new and escalates the risk narrative around Bitcoin custody and security. With Strategy holding 842,138 BTC, any erosion of trust in Bitcoin's safety mechanisms could pressure the stock further.
