Im guessing if you send someone that bitcoin to someone else KYC would remain

They could trace the trail from the exchange if they wanted to without whirlpool, and you are on the hook for proving you still have that coin to IRA/CRA otherwise you will have to pay capital gains tax. In Canada that's 20% off the profit from buying price
The person receiving those coins you send p2p would be KYC-free from the receiver's perspective, but not yours.
