These days, there's been a lot of discussion in the group about privacy coins/mixing coins and whether they are truly "original sins." Frankly, I think ordinary users shouldn't have too many illusions: on-chain privacy is more like "moving you from under the streetlamp to the shadows," not making you disappear. Whether you've used certain tools or if your funds have strange sources, compliance teams often look at "risk profiles," not just your verbal explanations. Anyway, my own expectation is: privacy can increase costs, but it can't stop someone who really wants to investigate you; and once you go through KYC/AML for deposits and withdrawals and hit risk control, the unlucky ones are often the most honest.
