I think you should read your post again and modify it because i cant really understand what is your question.So basically you are paying someone to locate you a seller of bitcoin? I dont see the point of that kind of service since you could directly look for a seller and buy from him.
I would also say or should i say i literally also don't get the idea of this statement of where the heck is the topic going to. what i simply understand is;
"if I am going to buy drugs or any goods in the internet and then i will use bitcoin as the payment, will it be consider as legitimate transaction over person to person not knowing their real identity? and will i be trace if i put my location on transaction history (virtual receipt)"? is the topic simply goes like this?
I'll comeback to this thread if it goes like that.
No, I think his question is whether the service itself is legal if it's done thru a third party.
Technically it is legal for the service provider to give you the said
located product or bitcoin. I believe there are already platforms that provide the same service. There's no harm in that. But, from what I see, the question lies on whether
Bitcoin is legal at your jurisdiction. To answer OP's question, even if you were to pay the
service and not the
bitcoin in question, it won't justify the transaction if bitcoin were illegal. If you were to buy drugs from a third party, wouldn't it be the same thing? Even while you pay a person for the buying (the service), the drugs itself makes it an illegal transaction.
