Bitcoin Q&A: Multi-signature and distributed storage


What happens when wallets (personal or at an exchange) are hacked? What is “sweeping” with regards to private keys? After a hack, is it possible to track the stolen bitcoin and identify the hacker? How do you keep bitcoin safe in a group / corporate environment? Is it possible to create a multi-signature setup with Trezor and Electrum? Could passphrases be brute-forced? What is happening with browser extension deprecation?

You will have to evaluate which tools are the best based on the amount of cryptocurrency you own, your circumstances, and your threat model.
