If the OP knew what his neighbor's real goal in learning bitcoin was, he wouldn't hesitate and come up here to ask our opinion. I think what he's afraid of is that his neighbor is using bitcoins for their illegal work and that will affect OP's safety if his neighbor gets caught. The OP is in a dilemma because he doesn't want to offend his neighbors, nor does he want to lose his own safety. But in my opinion, to avoid the risks, OP should refuse rather than teach him bitcoin.

First of all don't write off anybody when it comes to learning no matter how you see that person.
Your neighbor who's a drug dealer and wants to learn about Bitcoin from YOU and not the other guy you taught, is something you have to prepare your mind to do, I mean what's there? Like what do you expect when you are done teaching someone something good won't that person telling another?

He might be a drug dealer but can you tell if after teaching him all about Bitcoin that he might stop going into drugs? You can be a life changer at this point, drug dealers make so much money like you asked "Why would a drug dealer want to learn Bitcoin? " who knows if he wants to stop the illegal way of making money. Well if I'm to be you OP I'd go ahead and teach him all I know about Bitcoin.

This is a very excellent question that reveals all the problems of cryptocurrency anonymity to an outside ignorant observer, just like the state. We use cryptocurrencies only for good purposes, but there are also those for whom bitcoin is not a means that can change the world, but simply an anonymous payment tool. Such people don't care how it works. They don't call cryptocurrencies digital gold, they only care about practicality. It is because of them that there is regulation.

So my answer is no. I wouldn't teach him cryptocurrencies.

Just simply ignore and reject out such request and no one could force you if this is against your principle knowing that someone is really that having those illegal doings on which it is really just that right that he
shouldn't really be knowing about Bitcoin because you would really be that telling him about on how to avoid on not getting caught on which means that you are really that helping someone not only via means of anonymous payments but you are worsening out that drug addiction due to that kind of decisions if ever you would tend to help him.

If its against your principle then you could just simply reject out and tell something that wont offend him.I know the hesitance on trying out to deny or rejecting him knowing that you are dealing with someone
who does have connections and having that addiction towards drugs on which you would really be mainly be thinking for your safety too on which i do understand on how you do feel on the time
that you are on such situation on which you would really be boggling your mind whether you would be teaching him or would reject him out because its against your principles in life
but at the same time you are minding about your safety. So this would really be a tough personal choice to make.

I completely agree about taxing millionaires, which will later go to medical institutions, landscaping poor areas and all kinds of support for the population who are not able to take care of themselves. But if you dig deeper, there is a problem with this. You see, if the luxury tax increases, then billionaires can easily renounce the citizenship of the country where they live, but at the same time stay in place. And take another citizenship, for example, UAE or Turkish. And then the American treasury will not receive a lot of money. I think that's why they need a luxury tax.

Quite true but to me is best to just do the needful which is to teach that individual who wants to learn. It can only work smoothly if we can read the thought of the next person to know what he's thinking or planning to do next but that's not possible. There's nothing bad in teaching the drug dealer guy, not that if he uses it to do something illegal is your fault, all you did is showing him the best way to make money without being chased around by the cops. He might even change his mind depending on how you use your words, can get into his skin to convince him about the drugs thing


He can say yes he'll change or not to use it for evil act but those are just words, after saying that he might go and do something different from what he said, so is not that easy to say something and abide by it. And at the same time he can be on the drug business and also on cryptocurrence business too, so we can point out his intentions.
