I didn't pick the right coins today, I'm losing money 😔

Yesterday's trading method was to withdraw all amounts that exceeded the principal. The reason is that my main reason for losing money is that my position is too heavy, and it's easy to make nine gains and then lose everything at once. Therefore, I withdraw the hard-earned income every day. The principal is like a fishing rod; when the fish 🐟 bites, I need to take it home to prepare for a meal.
