Yes I introduce it to them but I didn't bother to explain Bitcoin to them so well since don't want to do any hard selling just to make them believe that Bitcoin is good. Its up to them if they do further research since if they show interest and want to learn more provably this could change their life especially if they are starting to earn on Bitcoin and other altcoins out there.
With Internet nowadays, it's easy to search about Bitcoin and with rapid growth of AI, ChatGPT for example, people can ask these AI bots for any question they have and they can receive acceptable good answers as their start of exploration on Bitcoin.
Introduce Bitcoin to them is enough, if if they are fearful enough or lazy enough or both, to don't do their own research and practice buying and selling by themselves with small money first, they can ask you to purchase bitcoin for them on behalf of them. It's risky unwanted task and I don't recommend you or any people doing this. People if are interested in Bitcoin, want to get profit from Bitcoin investment, need to do it by themselves. By this practice, they will understand more about Bitcoin, including risk and it's better for them.
If you purchase Bitcoin on behalf of them, store bitcoin for them, if by any reason that wallet was hacked, you will be responsible for it, and they don't mind to listen to your explanation about that accident.
