Coldcard firmware vulnerability led to the theft of BTC worth $88 million from users' wallets, pushing the industry's trust crisis to the forefront.
Although skeptics like Bruce Fenton view this as evidence of the failure of the "be your own bank" philosophy, early Bitcoin developer Peter Todd countered that even the scale of such hardware failures is far less than the systemic risks posed by centralized platforms.
History shows that exchange infrastructure collapses have caused far greater losses to investors than any software technical flaw. The $200 million loss caused by Canadian platform QuadrigaCX is direct proof. In fact, the loss from a single centralized platform is more than double the loss caused by the large-scale Coldcard hardware failure, directly indicating that handing over private key control to third parties remains the primary systemic risk to capital.
So, are crypto investors too lazy about financial sovereignty? Todd believes that the issue of personal fund security lies not in the complexity of blockchain architecture, but in the lack of basic culture for handling sensitive data. He compares key protection to preserving physical documents like birth certificates—users simply need to write down 12 words and avoid losing them.
Todd also uses driving as an analogy: driving a motor vehicle requires hundreds of hours of focused training, and a single mistake can cost a life. He wrote in a tweet: "Two obvious strategies that any adult can think of. If you were finding a hiding place for cash at home, you would also consider not putting all your money in the same place."
In this context, self-custody appears to be an extremely simple process. Todd believes that introducing multi-week educational courses similar to driving schools could reduce the proportion of critical errors caused by human error to almost zero.
In Todd's context, poor entropy or unforeseen risks still exist, but this does not negate the superiority of sovereign custody: the vulnerability lies in users' lack of responsibility, not in the Bitcoin code.
