Yes, once I invested some money in a new coin in crypto. I did not do proper research about that coin. I just saw new coins and traded aggressively. Later I lost. Then I realized that if we do something in a hurry without getting proper information about coins in crypto, then we will definitely lose.

If I had not been in a hurry at that time and had not tried to learn about the coin, then I would not have lost that loss. If I had invested that money in Bitcoin at that time, then my investment would have increased a little. So we should never be in a hurry about anything. "The elders say that haste is the work of the devil". If you hurry, mistakes and losses are bound to happen.

I still regret it sometimes.
