Cash it first and then buy the Bitcoin again.
Also don't use just 1 address, share it to many addresses.
How do you cash it? Do you do that in exchanges? Then the exchange will have your information. The exchange will also know which address you send the bitcoin t.
Yes. The exchange would be able to trace it. However, you can use an alt coin exchange and exchange it into an alt coin, cash it out on another exchange. While using different VPN IPs. It is slightly risky due to the volatility, but it is still better than mixers.
Don't use an exchange, just sell it to someone that you'll meet in real life.(Do it too for the buying time, except for this time don't use the same person)
