Why people always advice newbie against inpending dangers associated with trading, is the Risk involved. In my own understanding I see that those who are educating you on what to do have seen or have come into conclusion to that beyond reasonable doubt that trading is a quick way of loosing your fund. what the old investors have seen in trading, they take it as a priority to teach you about the inpending dangers ahead. But never mind you will not understand. There is a parable that says " what an elder sees while sitting even if a child climbs the higher tree he can never see" meaning that no matter how they explain to you you will not understand until you encounter the dangers before you learn.
But if you are smart you learn from the mistake of another person rather than fall thesame victim before you learn. What ever dey tell you is for your own good. But if you choose trading it's fine but don't forget that holding for long is the best option.
For those stubborn people who don't want to listen to other people's advice and think we're stopping them from getting into bitcoin. The best way is to let them experience and learn lessons for themselves. Sometimes free advice will not be valued, things paid for in money will be more appreciated. That's why I rarely advise new people because they are very stubborn and always think they are right. I think everyone needs to have experiences and we should let them have those experiences, not prevent them.
