The currency of choice on the dark web is the crypto-currency,
Bitcoin.
The reason for this is that it is untraceable and anonymous. Neither
party knows who the other one is, ever. CSO Online claims that
Bitcoin
is one of the major reasons for the incredible growth of the dark web.
Many dark web marketplaces use shopping carts, ratings, reviews, and
even forums. Some vendors use an escrow service to hold the funds
until both parties are satisfied. If you are victim of ransomware and
identity theft, you will be asked to pay via Bitcoin.
