Yeah, the 5$ wrench attack might have a big "return of investment"
It reminds me that a few years ago info of some Ledger customers was stolen... not nice to know that somebody out there knows that you own a hardware wallet and where you live...
Actually I'm wondering how customers' info are secured on crypto exchanges, they basically know your wallet address(es) and where you live.
It might be dangerous for personal safety if they sell this info to some criminals: from the wallet address they can see on the blockchain-scan how much you have on your wallet and might come to your home to extort your wallet's seed phrase.
