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.
Sell same amount on same CEX. Have proof you sold what you bought and have nothing.
Buy same amount on non KYC exchange. Never use KYC exchange again.
That's actually a great idea I hadn't thought about. However, in my case, I had non-KYC Bitcoin, which was then deposited and sold on Bitstamp as Litecoin. After that, they were moved to Binance, turned into BUSD, and moved to Metamask. They stayed undercover for quite a while and multiplied through staking and yield farming. My largest mistake now is that, after Luna crashed, I moved all my money from being undercover on Binance. As a result, I'm now presenting a larger value than I ever had on a CEX. For instance, let's suppose that I deposited $4,000 and now have $6,000 worth of crypto. In my case, it's practically impossible to permanently delete my traces.
