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 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?
I don’t see any reason at all why you shouldn’t teach the pros and cons of cryptocurrency or bitcoin like you put it to someone who has the zeal and is willing to learn. It doesn’t matter if it’s about the said person using it for his underground lifestyle or not, that still isn’t going to make him not continue in the drug trade but, it could be a reason for him to stop.
I don’t know of any drug dealer that is very excited about the trade. Of course the money comes but the things they have to handle as per security issues, rival wars and the safety of there family is something they have to look out for and when it happens that they find this new means of investing and even making a good enough fortune, it could serve a reason as to why they have to quit the trade.
I don't think what you're saying is what the OP is thinking. What the OP is worried about is that if he teaches bitcoin to that neighbor, it means he has a close relationship with drug criminals, and if that neighbor is arrested for drug trafficking. Bad things are bound to happen to the OP. If it were me, I wouldn't care what they used bitcoin for but teaching bitcoin to criminals could make me an accomplice and possibly jail, so I wouldn't do that. I need to protect my own safety before thinking about helping others.
