Okay, I have a genuine question since the majority here mentioned mixing services such as Chipmixer. Let's suppose that I have a fully verified account on Binance; they have my ID, tax number, full address, and everything, and I purchase at some point $10.000 worth of bitcoin. How can it become untraceable since a CEX that has all my personal details knows that at some point I bought X amount of bitcoin? The mixer will only make the transactions untraceable back to me, but a centralized organization already knows what I've bought in the past.
