RE: How to create and use a cold wallet on Hive

Multiple account key permissions is what I would expect to greatly enhance this when the SMTs arrive.

Having a rule (with an activation process) for a certain amount of keys to be required for the "unlocking" factor of something like the savings account of a certain account would be a feature much more interesting. Could even (on deeper complexity) include the ability to lock just a certain amount. Similar to the code already implemented on the conversion of HBD to HIVE and the savings account unlocking system (a mix of both situations in some sense), along with a time to broadcast a 2nd or even 3rd key to start the unlocking process... would perfectly protect an account.

Then, because accounts can still be stolen, and you don't wanna for your funds to be stolen on that situation, while the new owner forges new keys... an automatic process would move the "savings" amount to the account that DID NOT yet change owner keys, simulating the reset of the MFA account system back to the normal basic system, giving the opportunity for the real owner to plan for some more protection.

Simpler then EOS, and could reuse most of the current HIVE code with some extra tweaks...
