yes when bitcoin was first launched it spreaded like a virus into the whole underworld where it has the complete place for all type of illigal activities and more but thats not truly our point. tor nretwork has many sites running and most ofvthem accepts bitcoin as payment
I think we shout admit the fact that bitcoin is mostly use for good purposes, and may be a little number of bad people using it for illegal activities just like other fiat currency, I think we should always look to the good aspect of everything.
I think we do not need to think about other people's negativ. moreover bitcoin transactions are anonymous and no one knows about the destination on your bitcoin transactions, so it is illegal or not, it does not matter
there is a bad and good thing in every bitcoin transaction, even its for illegal activities and we agree for that. all this thing its because bitcoin is anonymous, then people thinking better to pay with bitcoin to make good or bad activities or make an illegal transaction, but unfortunately we don't know about this, we only know that in blockchain, there is many transaction from small until big amount.
We will not know because in the first place we are not interested to know it. We are not cops anyway we have our own business online, and in my case I just gamble online and I don't know it it's illegal or not.
