I'm new to this investment thing. Well, I've been investing for two years. I had a portfolio in Robinhood that I finally had to sell. Right now, in the face of this crisis, I have focused more on buying and selling, sometimes I sell from one day to the next, sometimes it lasts 2 to 3 weeks. and I'm doing it to learn more and the truth is that it hasn't gone so badly for me and I've learned more from my mistakes. You also learn not to say that I'm not interested in creating a portfolio, of course I am.
