Then Strategy should use distributed custody models like Unchained, Onramp, or Anchorwatch. The fact that they do is why I decided to stay humble and stack sats. This is the problem # bitcoin solved:

"A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution. Digital signatures provide part of the solution, but the main benefits are lost if a trusted third party is still required to prevent double-spending. We propose a solution to the double-spending problem using a peer-to-peer network."

What problem does Strategy solve by "buying BTC" from Coinbase? It seems to me they are only re-introducing the double spending problem.
