firstly im no expert on crypto assets but it looks to me that this device solves the problem of having to store your digital assets with an exchange, the story of quadriga recently demonstrates the dangers of that, investors lost circa 150m USD when the founder died and took the passwords with him to access the accounts. It seems to me that this is the exchange replacement in your pocket. If im right its massive.
