Then if they've lost their private keys, they can't get access again employing their PoP.
And the masses will lose their private keys. Sheesh are you not aware that most people create a new Facebook account when they can't remember their password. This happens quite often, which is they they end using a password that is easy to crack using a dictionary attack such as "1234mydogSpot".
Of course, but this is no different with bitcoin and altcoins.
But HumanIQ claimed some amazing breakthrough where billions of masses wouldn't have to deal with private keys and could sign transactions with only their face. Which is BS.
