The crash will teach alot of people a bitter lesson and they will learn from it,
they will learn the following
1. Never to love a coin
2. Never to be greedy
3. To cashout on profit always
4. To stop following hype
5. To know that what goes up must come down etc
You're absolutely right. I made mistakes on all points unfortunately.
Once I had a token that I really loved, I loved the community and the project, so I didn’t sell it when it decreased by 80% or more. It was a sign for me to sell off, but I continued holding and then it was hacked.
Also we shouldn’t be greedy and fix our profit, you are right, it is better to have a small profit than to overhold.
