Because of bitcoin does not give public details of people who make transaction with it, some people do say it promote crime. People needs to understand one of the features of bitcoin is freedom that anybody can get access to it, it does not discriminate. The privacy features of bitcoin is very important to humanity, which I know one of its advantage is for safety by using cryptography that makes all transactions safe and encrypted.
Privacy in transactions of bitcoin is much important, if their was no privacy it would have cause several criminal attacks. For those who think bitcoin encourages crime because of hiding public data of users don't understand the importance of bitcoin being private. Before bitcoin started existing monetary crime have been existing. Bitcoin is not a reason for monetary crime, bitcoin is just for everyone and does not discriminate but accept everyone.
Right and wrong.
It definitely enables crime or makes it easier. To say it has nothing to do with crime would be the same as saying guns have nothing to do with murder. They can be used for murder, but not necessarily have to. Same for bitcoin, it can be used to commit crime, but doesn't have to.
In the beginning for example bitcoin was the go to payment for silk road (as we all know). Well, dealing drugs is a crime. So bitcoin had something to do with it.
I am not saying bitcoin is a "crime currency" or is encouraging crime, it's far from that.
Just saying the topic name is wrong, it definitely makes it easier to do something crime related f you really want to. Like for example money laundry, buying illegal stuff, circumventing limits of bringing valuables into a country, and so on.
