That has made it attractive to those who want to keep their identity secret, including those buying and selling illegal goods and services on the internet.
Its really a sad thing seeing people use good technology for such dubious and scammish activities. When cryptocurrency gifted us the transactional attribute of pseudonymity, the goal was to bring back to the users the power of privacy against entities that intends to collect and take advantage of our information and financial activities.
It was not to conceal our identities to be able to perform such shady and illegal activities. I do hope those people change for the better and help shape up the crypto community in to a better form.
