Good afternoon, can someone who understands the subject help me? I'm new here and know practically nothing, I'm trying to learn but it's very difficult because it's something new, but here we go, I'm buying cryptos and saving them in the hope that they go up a lot, if that happens, one of my coins explodes and grows to the point that I change my life, how will I act quickly to get the money? Do I sell them? Do I convert them to BRL? How does it work? Could someone help me?
