If you are aware that your neighbor living next door is into drug dealing and he come seek your advice how to buy Bitcoin, will you teach him?
What comes straight to mind is embezzling the ill-gotten money, but is this even safe? My other neighbor knows I am into Bitcoin and he learned from me, I guess that's how this other neighbor knew, I told him to go meet the next neighbor but he said he is not ready to teach.
What will you do if something like this is happening around you? Why would a drug dealer want to learn Bitcoin if not for a safer haven for running the business?
My mind isn't settled as I keep thinking different things, what is on your mind readers?
actually, you are in a completely wrong position, on the one hand you want to be a good citizen, on the other hand you want to teach bitcoin to other people, but if i were you, i would not teach that person the basics about bitcoin and how to do it he transacted with bitcoin because it was certain that when he was caught by the police, the police would also chase me because they thought it was a gang of drug dealers. bitcoin was not created for crime, but to improve the world's financial system.
Bitcoin is just an asset and what it is used for is up to each person, we cannot prevent anyone from using it for their criminal purposes. Fiat or bitcoin or any other tool is not made for criminals, all those mistakes are human behavior. Yes, OP should have turned down that offer, it's not because OP's neighbor is a criminal that he doesn't have the right to use bitcoins. It concerns OP's safety, so please reject immediately without thinking.
