@ bitfair

why would it have to be all owned in one address?

Say for example i would actually own 10 000 shares,
but for safety i would have them split to 100 wallets
in different cold storage places - since each is quite valluable.

As long as i have one signed message from each wallet that
states the same thing, i am one person!
Can you prove the opposite?

Regarding information trust within the group is an unproven
assumption.
