For all people selling in the red: If you don't learn to deal with your emotions, you will have a bad time investing in anything.

There is a good chance a young person without any prior investing experience and not much life experience is panicking right now. Close your eyes, take a deep breath and count to ten slowly.Maybe you sold already and wondering if you should buy again, maybe you are thinking only about your crypto for the last days. No amount of sick gains is more important than your mental and physical wellbeing.

Ask yourself one simple question: Will my life change for the worse if all crypto goes to zero? If the answer is "yes", than you are overinvested. Take money out until the answer is "no". What remains in your portfolio is not money, it is the future. It can bring great things, it can suck sometimes, but we don't live there. We live in the now and you can be relaxed now by knowing that you put something into your future.
