the most simple way to make your BTC vanish from stalker is to deposit at an exchange all your BTC then buy another crypto that is stable and move the new crypto you've bought at another exchange and sell it for BTC you will loose the fees plus the difference from exchanges but if you are careful you can even finish this process in profit, withdraw the BTC to another address you own!
no one can trace this!
I suspect that in the future, people who believe that this is a guaranteed way to hide the source of their bitcoins are going to be rather surprised at the capabilities of forensic accounting and a lot of computing power.
