A recent security breach involving Coldcard led to the movement of $120 million worth of Bitcoin, significantly affecting the cryptocurrency’s memory pool. This development highlights ongoing vulnerabilities in crypto hardware wallets, according to CoinDesk.
The hack caused a notable spike in unconfirmed Bitcoin transactions, as the memory pool—where pending transactions await confirmation—experienced increased congestion. Such events can influence transaction times and fees across the network.
For Japanese investors, who have shown growing interest in hardware wallets for securing digital assets, this incident underscores the importance of vigilance and security in managing cryptocurrency holdings amid evolving threats.
