Not all friends in my friend circle have the same attitude, so I didn't inform all my friends about Bitcoin. I have some friends in my circle of friends who were interested in learning about Bitcoin. I only introduced them to Bitcoin, but I did not inform them about Bitcoin unless they were mentally prepared. However, I have not suggested anyone in my circle of friends to invest because investment is a purely personal matter and there is no point in me interfering in it.
They need to learn first, and invest second.
I do think that some of them would come to such a conclusion eventually.
Yes, that's right, first you know, then you invest based on that knowledge, and you invest solely at your own personal risk. If you invest without knowing when to enter the market, at what price to enter, and what wallet to choose, then investing in and storing Bitcoin will be risky. Therefore, before investing in Bitcoin, friends should be asked to learn at least a little about Bitcoin, just like academic studies.
