Coinkite CEO Tells Coldcard Users to ‘Move Your Funds Now’ Amid Security Alert, BOJ Keeps Rate

Glowing Bitcoin coin in a cave between server racks, golden crystals, a mine cart, and pickaxes.

Coinkite co-founder and CEO NVK issued an urgent public warning to Coldcard hardware wallet users: “Move your funds now.” The directive arrived alongside a CoinDesk live update confirming the Bank of Japan left its benchmark rate at 1% and that Governor Kazuo Ueda’s hawkish signals landed softly. The combination of a critical security alert and ongoing yen carry trade dynamics set a tense Friday tone for the bitcoin market.

Urgent Coldcard Alert and Security Concerns

The severity of NVK’s warning recalls past vulnerabilities in Coldcard devices. In a documented incident last year, a Coldcard firmware bug enabled the draining of 594 BTC—worth roughly $38 million—in just 25 minutes. That episode, which BTC-Pulse covered in detail, exposed how even sophisticated hardware wallets can harbor critical flaws. (Coldcard Firmware Bug Drains 594 BTC in 25 Minutes, $38 Million Stolen). Coinkite has not yet released full details of the new threat, but the immediate call to move funds suggests a similarly severe vector.

Despite the alarm, bitcoin’s price showed little panic. It held above the $65,000 mark, reflecting broader confidence in the asset’s safe-haven appeal even during wallet-level threats. Users who heeded earlier warnings about hardware security were already accustomed to Bitcoin’s resilience, as tracked in recent BTC-Pulse analysis that highlighted steady price action amid corporate tech spending swings.

The high-stakes alert also reignited conversations about Bitcoin’s protocol future. Michael Saylor, MicroStrategy’s executive chairman, recently pushed back against the BIP-110 proposal that aimed to clean up what some call “spam” on the network. Saylor called the plan “a bad idea,” underscoring how even foundational network improvements face contentious debate. (Michael Saylor Says BIP-110 ‘Spam’ Cleanup Plan Is ‘a Bad Idea’). The divergence between infrastructure-level disputes and consumer-device security highlights the multiple fronts on which Bitcoin stakeholders must remain vigilant.

Bank of Japan Leaves Rate Unchanged, Yen Carry Trade Alive

The macro backdrop provided a contrasting steady note. The Bank of Japan maintained its benchmark rate at 1%, a decision widely anticipated by markets. Governor Kazuo Ueda’s remarks, while retaining a hawkish tilt, did not signal imminent tightening—preserving the yen carry trade that has funneled liquidity into risk assets, including bitcoin. With the yen remaining a cheap funding currency, global speculative flows continue to underpin Bitcoin’s price stability.

As both security and monetary policy narratives converge, Bitcoin market participants face a dual watch: the immediate integrity of their self-custody solutions and the enduring influence of cheap-yen capital. The speed of NVK’s warning—issued on a live market feed—serves as a reminder that in the crypto economy, operational risks and macro currents can shift with equal urgency.
