> Pete Kayll, a musclebound veteran of Britain's Royal Marines, had an unusual instruction for the Bitcoin investors gathered in Switzerland in late October. "Just bite your way out," he told them. It was the final day of a weekend-long cryptocurrency convention on the shore of Lake Lugano, near the Italian border. A small group of investors had lined up in a conference room to have their hands bound with plastic zipties. Now they were learning how to get them off. "Your teeth will get through anything," Mr. Kayll advised. "But it will bloody well hurt."

> Most people don't go to an international crypto conference expecting to learn how to gnaw through plastic. But after hours of panels devoted to topics like Bitcoin-collateralized loans, these investors were looking for something more practical. They wanted to know what to do if they were grabbed on the street and thrown into the back of a van. Already paranoid about scams, hacks and market turmoil, wealthy crypto investors have [2]lately become terrified about a much graver threat: torture and kidnapping .

These threats are known as "wrench attacks," which is a reference to a [3]popular XKCD cartoon where a thief skips the hacking and just uses a wrench to force out the password.

According to the NYT, the best way to stay protected is staying low-profile, minimizing visible signs of wealth, using basic physical security tools, and preparing for self-defense. The report specifically recommends avoiding flashy displays of wealth like luxury watches and cars, watching for [4]honey-traps , using hotel door stoppers, practicing escape techniques such as breaking zip-ties, hiring discreet bodyguards, and relying on panic-button apps like Glok to summon help quickly.
