Privacy has existed on the protocol level for Bitcoin since day 1.
Run your own node.

The only people who don't have privacy with Bitcoin are the ones who aren't running Bitcoin.

Running Bitcoin = Running your own node.

Now with platforms like start9, you can get a full Bitcoin Core node behind tor out of the box after a few clicks.

There are no excuses.

The fact that you gave up your ID to a KYC exchange or used a samourai node or any other node thats not yours  is not Bitcoin's fault.

Its yours.

If you use the internet without a condom (vpn/tor), you are going to get sick (rekt)!.

If you give your xpubs to third parties, youre going to get rekt!

Bitcoin in perfect money.
It only takes you to fuck it up.
