It is very noble to tell your friends about cryptocurrencies in the same bitcoin.
Just like you, my friend enlightened me on the topic of cryptocurrencies many years ago. Then bitcoin was worth about a hundred dollars. But then I didn't believe him in the success of biteoin.
Nevertheless, I am here, and I am grateful to my friends who worked on my understanding of the blockchain and how much it is a breakthrough technology.
You are doing a good deed, but always warn your friends about the risks that cryptocurrency carries. After all, this is a dangerous financial instrument.
His actions are good, he is trying to help his friends. But honestly, I don't think bitcoin is suitable for this situation because those 2 friends are unemployed, and we don't know what their life is like. As many others have also suggested, they need a job rather than focusing on investing in bitcoin with their savings. I don't know if OP thought of that situation. What if bitcoin investment is not profitable or will take a long time? We all know that the unemployed desperately need money, and they can't wait to get it, and it would be a terrible prospect for the OP's friends if the investment didn't go as they expected.
