Bitcoin would have looked quite stupid, if there were anything you could not buy or trade for it. Imagine people only used cash for medicine and PayPal for paying for their booze. Bitcoin does not discriminate against any product or service. This whole debate about Bitcoin being used to buy illicit goods and services on the Dark Web is becoming stupid. Most people can go out, get a fake identity and open up a PayPal account or get a homeless guy to open up a bank account for them.
Money opens up a lot of doors for illegal activities and people will find any possible way to capitalize on these loopholes. If they chose to use Bitcoin, and they are stupid enough to think that it is anonymous, let them do that. ^hmmmm^
Actually they aren't stupid to do that. It's so difficult to transact in the dark web before bitcoin. BTC opened them up for all the opportunities.
How did these people transact before Bitcoin was around? They used hacked or stolen credit cards or PayPal accounts. Those things are freely available, if you use the correct methods to obtain them.
You cannot blame the Bitcoin technology for the deeds of people... The people will use whatever method that is available to obtain the illegal goods they want. If you are hooked on drugs, you will use
the quickest method to get to that drug. { In many cases people are robbed and their physical credit card used to buy drugs on the Dark web } Is this not more harmful?
