I was introduced to bitcoin by a friend, but what I gained from knowledge to experience is that I taught myself and used money to buy lessons from my failures. But I'm not like you, I don't want to teach others about bitcoin investing, even if they come to me independently. Because I believe they are not like me, willing to accept losses to learn lessons and experiences in the market, what they want is to make money like me, but they are not willing to take losses as I did. In investing, no one can win the first time, to succeed, you need to fail first. So I can only suggest they do their own research from youtube and social networks, I don't want to be blamed.
