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?
This market may be of positive influence in your funds, however, you can't tell the same for your friends.
There will be other good times to introduce this market to your friends, but for now, look for other means of finding a stable income.
Whether it is illegal or not, bottomline is they are unemployed and yet you'd want them to engage into an investment. Investment will always have its own risk and that would also mean you are somewhat digging a deeper hole for them if the unfortunate would be the outcome. It is okay to share the idea but given their circumstances, they'd more likely be expecting much from it. It won't always be winning in this industry. But I do agree that they should be more advised to get a job which would give them a stable income and from that, they could as well engage to investments. In such way they'd be more capable of handling things and managing the risk of being on a worse situation. The idea that there are people who made fortune from this industry is the misconception 'coz behind their success are huge number of people losing. This simply means that nothing is assured in terms of profit making in this industry so better be careful still.
