COLDCARD: 594 BTC Drained in Hardware Exploit

COLDCARD hardware wallets lost 594 BTC worth $38M in a 25-minute exploit tied to firmware 4.0.0 from March 2021, prompting CZ to advise splitting funds across wallets while noting nothing stays 100% secure. BTC price prediction models now face added pressure from this incident as traders reassess hardware wallet security risks and Bitcoin private key generation flaws amid ongoing crypto market volatility analysis. On the 4h chart BTC sits at $63148.44 inside the Bollinger band with EMA50 at $64113.51 and EMA200 at $63863.18 acting as resistance while MACD death cross at -355.57 keeps the structure bearish and RSI at 40.41 shows neutral momentum, so price testing upper band resistance near $65326.96 likely faces rejection before any move toward lower support at $62462.31.
