I also have a friend who is like that, but he invited me and taught me a little how to get bitcoin, so I also tried to play trading, and made a little profit. sometimes we have to start without having to be taught and have to try, even though it has risks.
It's easier if there's someone who's willing to spend their precious time teaching what they've known through their experience in the market. This is a very rare moment when a friend, a true friend wants to do it for free. Because there are folks that have been monetizing with their experience even if they're just the basic ones. Those are not reliable people and don't really want to help people and their friends and they're only wanting to take advantage of newbies.
