I think the most important thing that can be learned is learning from experience. Many people have never learned anything by being told, they have to find out for themselves. I think many people who entered the crypto world before 2015 have passed this phase including me and I'm not worried now.
Why not worry? Think about waiting a few more years to get your money back. Then you will feel that you made the mistake of investing in the crypto, because that money you can invest in other things.
what you do is up to you, whether it's selling it or exchanging it for other coins for fear of losing all your rights. but the most important thing is not to leave the market because if you leave the market you will never be able to return your assets.
