This is exactly the part I don't like in Bitcoin: why is everybody so curious about that happens inside this or that person's pocket?!
Would you like if everybody would look into your pocket and speculated what will happen next or why did you spend certain money?

For this obvious reasons I expect that VIP wallets stay safe and unknown. And there's quite a big chance that also it's not all the money on the same address, so it's much more difficult to narrow the search in case somebody tries that. I also expect that the money is held by 3rd party custodians that know how Bitcoin works, not directly by Tesla/Elon Musk.
