If your friend is unemployed, you should help them get a job rather than teach them about bitcoin. Bitcoin investing is not a job that can bring a steady income, it is merely an investment, and investing is a gamble with winners and losers. Furthermore, if bitcoin is illegal in your country, then you are burying yourself trying to break the law by teaching bitcoin to others. I think you should stop this idea as soon as possible the better for you.
That is the problem in this situation, crypto is illegal in their country. And that means, you will be introducing them to "illegal" thing.
So instead of introducing them to bitcoin, it is much better if you will give them other options to find a real job.
Being unemployed means they don't have stable income, so do you really think it is smart to get involve in this market knowing this market is illegal in your area?
