I used to force people to buy bitcoins just like you said, I realized over time that this was unnecessary and that they were the only ones who lost.
I enjoy telling people about bitcoins in general, its structure and technology, that's a separate issue, but I leave it to them to buy, everyone is responsible for their own investment.
We will be responsible if something goes wrong, so it's best to forget about it. After all, I'm not an advisor, so I don't have any responsibility to give people financial information.
