I made a new email to only log in on TOR just for signing up on dark web websites, I will never log into this email unless im using and/or connected to the tor browser network.
I made a software wallet with a TOR proxy to store the bitcoin I buy, and bought a hardware wallet to store the bitcoin that I will be passing through a bitcoin mixer service with this wallet to keep my dark web activity unassociated with my clearnet activity. I plan on buying a few things from a few verified stores.
