There are exchanges, custodians, etc that hold insane amounts of BTC or ETH in a single address.
We are talking billion dollars+ worth in a single address. So if either chainskey security is compromised in a way that it is conceivable to brute force it, there will definitely be plenty of targets.
Stealing a billion dollar address is kind of worthless. Try cashing it out. Even if you are NK.
Yes, it would require those exchanges to move their funds around. I'm pretty sure they can manage it.
