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.
actually it would be difficult if he was our neighbor or maybe even he was our old friend. between wanting to help him change his life and at the same time OP definitely feels threatened because of his neighbor's involvement in the drug trade.
yes you are right the OP better refuse to teach with any plausible reason and ignore the neighbor regardless he looks good or maybe he is his old friend. becoming close to people who are involved in drug trafficking is highly not recommended because one day they may drag us to bear the risk of being involved with drugs.
it's better to be vigilant than to regret it if we get dragged into a drug case.
