How would you respond to a crypto naive person who asked you how to make money from crypto?

Yesterday went out with a group of good old friend who were in the same hostel as me when we were in university. After our meal, I took out the cdc credit card to pay for the meal, a few of them saw that and told me they are interested and asked me how to make money from crypto. These friends are engineering geeks who are crypto naive and I am not sure if I should just asked them to stay away from crypto. I usually don't tell around to others i hold crypto. I am afraid they may invest in crypto without enough knowledge and blame me for it when they lose money. In the end, I told them about my own little DCA investment in bitcoin and warned them about scams. I told them about my own mantra, if anyone tell you something is fun and easy, they are probably just trying to sell you.
