A corporation is going to take the view that they don’t want a single individual, they’ll want to have a multi-signature relationship when it comes to the custody of their Bitcoin and they’ll have more sophisticated custodial rules.
A government needs a different application also. If you were a citizen of a city, and the city put a billion dollars of Bitcoin on its balance sheet, would you want the mayor to carry the keys around? And by the way, if you were the mayor, would you want people to know that you actually have the keys? I mean wouldn’t you be concerned about being kidnapped and having your fingers ripped off one at a time? Or having a family member kidnapped?
So in that particular case they’re going to be interested in a different thing. That’s another application. That’s multi signature application. Who should be signing it? In some cases it’s not even multisig across people. It’s multisig across organizations like three agencies, or three corporations or auditors might need to have some involvement.
Whether or not Macrostrategy actually uses multi-sig or they trust a third party like Coinbase to custody it for them, it seems Michael Saylor understands how it works. It makes more sense to me that they're using multi-sig, but until they actually state that, we can only guess.
He is a rocket scientist after all.
Referring to other institutions he also says this:
It’s not always the case that the right answer is cold storage, hardware wallet, self custody. It depends upon who you are.
And he did buy some bitcoin recently, personally:
The other day I bought $30 worth of Bitcoin. I bought it on one application and paid a .69 cent fee. I went and I tried Strike and I paid next to nothing. I thought that’s kind of cool. Okay so thank you Jack Mallers, we appreciate that. Competition. It makes us all better. Right? There’s pressure. And that pressure will continue. When will that end? That won’t end.
So he's saying, cold storage and self custody might not work for others (implying that they are probably doing it) without clarifying that they are doing it.
He also knows about mining with an S19 miner .. or understands the math behind it. I don't think he's mining.
Bitcoin gets more secure, and more robust, and more antifragile. It’s not inflationary, because the protocol is locked in. The only result is the network decentralizes.
