I know your feeling, ive make this stupid mistake when i buy a car this year at april with one eth, and i will never forgive my mistake with this move!
But you have a car, mate. You shouldn`t underestimate what cryptocurrencies have already given you. You didn’t lose your coins, you exchanged them for what you needed at that moment. Your feelings of regret are based on today's realities, which have changed since you made your decision. But at that time, your decision was justified and took into account the current circumstances. When you regret lost opportunities, it's easy to miss new ones. Therefore, while driving your car with pleasure, you can think about new investments.
