Using the digital equivalent of money laundering to hide their transactions and make deals off-chain by talking to people (or having their people talk to them). If you are wealthy enough you can afford whatever levels of indirection are necessary to retain your privacy.
I was curious about this: >"he reason crypto enthusiasts don't worry about the privacy implications is that it will still be possible to "buy privacy" and they believe they're going to make it big so it won't be a problem."
What would their solution be then? How would one buy privacy?
