This article mostly uses the story as a way to scare people into using banks:

Banks are tightly regulated by laws meant to protect consumers from theft and fraud. They can freeze accounts or reverse funds, set limits on the amounts that can be transferred in one day, and flag suspicious activities.

Crypto, meanwhile, is attractive because of the autonomy it affords account holders, said Ari Redbord, head of global policy at TRM Labs, a firm that monitors and investigates digital-asset fraud.

What's slightly different about this case is that they attackers were getting a lot smarter about using food and package delivery services as cover to get people to open their door.

“They would get screenshots from the person behind it, like, ‘Hey, this guy’s DoorDashing up at this place. Go pick up a fake order.” 

Records show at least two victims in the recent California attacks were expecting a delivery when the suspect arrived carrying the same item or a similar one. In the San Francisco and Los Angeles cases, the suspects called their victims on multiple occasions — from the same phone number — to confirm a time to accept their purported delivery. In at least three of the cases, the victims received food deliveries that they didn’t order prior to the attack.

KYC leaks probably played a role in these, but there's also this part:

The thieves ultimately made off with $10 million in Bitcoin and $3 million in Ethereum — holdings the victim later told police were publicly known.

But even if you don't talk about your stack in public, there's the chance that kyc data gets leaked:

The victim later told officers he believed he was targeted because information on his crypto holdings had recently been leaked, according to a police report.
