...all I can say to the newbies is that grow your brain before you try to grow your portfolio.
Good advice, but i believe newbies will be just like you, only after experiencing bitter loss of money will they realize that new knowledge is the first thing required in this market before you want to grow or earn money in the market. I myself used to be like that, didn't listen to anyone's advice, just followed what I thought and only when I really lost did I realize that everyone's advice is correct word for word. That's why I have very little advice for newbies, I also want them to experience to have the most authentic view of the market, I think there is no better free lesson than a paid lesson.
It was very common for us, we tend to open our minds and be even more careful after tragic losses. I understand this thing as I was also in that situation before but yes, as long as we do listen to others and are able to anticipate any possibilities that will happen next, in this way we minimize the risk and unacceptable ending.
We probably don't have a good start investing crypto but at least we still able to survive and continue trusting despite the bad experience.
