That will depend on your government and how aggressively they chase people who they know whirlpool their funds using chain analysis in the future… basically, we don’t know what the consequences will be, so you’re better off either selling the KYC and re-stacking non-KYC, or simply partitioning your KYC stack in a separate stack and start stacking non-KYC in a different wallet that never mixes or touches the other (my suggestion is to evaluate how much you still have left to stack and make a call based on knowing that likely in the future you’ll want both types of stacks)
