Zcash's privacy model treats your counterparty as the adversary; they know at least as much as any observer. Shielded transactions leak *nothing* to your counterparty, and therefore your privacy is unaffected by which address type they provide.

Drug dealers and criminals captured by network effects and three-card monte tricks are not enlightened privacy and cryptography experts to take your cues from. Unless you're as naive as they are, use your brain instead.

Privacy also requires shared values! You aren't anonymous if the people you're hiding amongst can be compelled to point fingers. Ring signatures are a dubious claim that if everyone only points a few fingers you're safe. This is not serious thinking and quickly falls apart.

Anonymity isn't about taking elaborate means to obfuscate your actions, it's just people doing the least to distinguish themselves from each other. Security by obscurity not only doesn't help but it can even cause you to stand out more.

They're probably stuck selling their coins to MicroStrategy because they can't do anything with it safely. And you're stuck defending shitty cryptography on social media because number might go up. Pathetic state of the space.

Recently people pointed at the 70k BTC transfer and said "oh yeah if Bitcoin isn't private then who was it?!" This exposes an ignorance about resource/information asymmetry. If you sold some real estate to that whale you would know it was them, just as a trivial example!.

"Oh yeah? If DES isn't secure then decrypt this!" The problems with DES and especially 56-bit keys were forseeable even if the average person didn't have the compute power needed to break it at the time.

If you're asked to "trace" or deanonymize a transaction on a cryptocurrency to prove it satisfies some privacy property, you are dealing with someone incapable of thinking critically without the empirical evidence of being extorted or kidnapped first.

Succinct ZKPs are one of those things for which even seasoned veterans who have worked with the math for over a decade still occasionally pause and reflect: "I can't believe this actually works.". Sometimes it feels like it wouldn't but for the hand of God pushing the pencil.

This is a totally different vantage point for Zcash to be working from. We're starting from something that is already extremely private toward something that *also* scales to the entire world. That's why world experts in cryptography and privacy believe in Zcash and few others.

There are ways to improve, particularly at the boundaries where it comes into contact with the rest of the world. But to be certain about your privacy you *must* start by using shielded Zcash. You almost cannot even begin otherwise.

For example, there is no quantum computer or powerful AI that will be able to look back at the Zcash blockchain 1000 years from now and figure out who made every fully shielded transaction. That information, among other things, never even touches the ledger. It's already gone.

In many ways Zcash's shielded transactions bump up against the information-theoretic boundary of what it means for something to be private. It's not perfect but in many meaningful ways we simply cannot make it any "more private.".

Zcash is humanity's first mathematically fungible asset. Much like when time and space switch places in a black hole, when money crosses the event horizon of a shielded pool its history begins an unstoppable, monotonic march toward indistinguishability.
