Jeremy Welch of personal key security system Casa describes the company's various services and products, including its $10,000-a-year premium service for HODLers of at least $500,000 worth of cryptocurrency and the Casa node. He explains how he came to start Casa, why using seed phrases for managing security of crypto hardware devices is so problematic, and how customers should set up the keys in their possession for the company's multi-signature solution, in which any transaction requires the use of three of five keys. We go on at length at about potential ways in which an attacker could still force a target, say, at gunpoint, to move money to the hacker's wallet. We also discuss why the company doesn't offer a multi-sig solution for ether, why people choose to run Casa's Bitcoin/Lightning node and where people are using Lightning.
