I agree.
And you are correct, the "bank balance" carrots dangle in the breeze to tempt anyone of such persuasions. Which is a very interesting "hide in plain sight" concept.
I doubt that the key part will or can be broken, like attacking a lock on a safe really. The hack will be a "tunnel" under floor or via an A/C duct or something. eg via the clipboard malware. these are the 'threats' that need to be addressed IMHO. once they are secure, then 9 billion can safely move there "money" to steem and have it in a 'glass box' for all to see. or at least the part they are not putting on the BTC roulette wheel!
