buy low, sell high, those who haven't learned will incur losses

Stop worrying, it has happened before. Soon it will return to normal. The person who lost was the anxious one who sold because they saw the price plummet, that one has no salvation left. I have been in the crypto market since 2019. During my first time experiencing a sharp decline like this, I also made the mistake of panic. And I realized that over the years it is normal, because it is part of the volatile cycle of cryptocurrencies. Keep the coins with you, they will regain value. The devil is in the mind. Do not lose to anxiety.
