Coldcard: Exploit Questions Air-Gapped BTC Wallets

Decrypt reports that a Coldcard exploit has reignited debate over air-gapped BTC wallet security, challenging the long-held assumption that offline devices remain immune to remote attacks.

BTC price action shows the asset holding at $63719.5 inside the Bollinger band, testing upper resistance at $63920.14 while the 50-EMA at $63706.17 and 200-EMA at $63705.35 act as immediate support. MACD golden cross at -95.29 keeps the broader structure bullish even as RSI(14) sits neutral at 53.46, suggesting any pullback would likely find bids at the EMA cluster before continuation.
