A $110 million question: How safe are crypto wallets, and what’s the best way to store Bitcoin?

A software flaw in a Bitcoin wallet that was considered extremely secure has left thousands of investors counting losses. More than 1,755 Bitcoin, worth around $110 million, were stolen from wallets using Canada-based Coinkite’s Coldcard devices, raising fresh concerns about how safe crypto wallets really are.

“The moment it loaded I knew I was screwed because I saw red lines for withdrawals,” Jonathan Goodman, one of the victims, told Bloomberg News. “Between 9:36 and 9:43 p.m. on July 29th, all three of my wallets were completely drained.”
