If the coin I am holding increase in value, I lock the profit I gain and convert it into a stable currency like usdt. When I piled up and reaches a desired amount, I convert to fiate and buy a bank investment
Having a profit is very nice in crypto , that's good when you see that you get a profit and you already convert it into your local currency, because sometimes other people lose their money because they don't sell their coin after knowing that their already have a profit .
