This is not a subject to discuss. No one should acquire Bitcoin without the knowledge of what it is and how it works. And never help people who has no knowledge about it. You told him to learn first, and that's the best thing to do in any situation.

Even if they buy it now without the knowledge, then it is best to just hodl until the market is in bull run again. But given the current market condition, I think it is best to wait for the market's correction. Never take risks for someone else's sake. Being selfish in some situation is not always bad. It's a good thing in this situation.
