Bitcoin Privacy: Upgrades and Challenges

Back when Bitcoin first dropped, those cypherpunks really knew its limits on privacy and scaling. The whitepaper even talks about privacy in section 10, saying the bare minimum is to use a fresh address for every transaction. But that only goes so far, cause if you mix a bunch of inputs in one transaction, it kinda blows that privacy outta the water.

Totally get what you're saying. But honestly, if you’re using coins from multiple addresses, it kinda shows that it's all from the same wallet, right? Like, if you grab coins from ten different addresses, it’s pretty clear who owns them. You could always coinjoin or mix them, but that costs time and money... privacy ain’t cheap.

I've never had issues with exchanges rejecting coinjoined funds. If they do, that’s more of an exchange problem, not really coinjoin's fault.

Fair point. But just because you haven't faced that, doesn't mean others won't. It's smart to double-check your coins, especially if you're thinking of trying out a new exchange. Trust me, it’s better to invest a bit of time in checking than risk losing coins due to AML stuff. Every exchange has its own rules.
