This has happened many times before with me. It sometimes hurt me a lot in the beginning. It often happened that the prices went up after the tokens were sold, so I was very upset about the situation, But that's when I started working in crypto. But now I understand that this is a market and prices fluctuate in the market. There is nothing wrong if you sell them first and then the price goes up because you took advantage of it religiously.
It's unfortunate and to be honest, happens sometimes with me. But You can minimize your loss if you sell part of your token not full. If the price goes up do not rush to buy back but wait for it to be stable. Because there will be many more chances in the future and if you failed to find that in this project then try another one.
Yeah, It always happen at every one, because crypto currency is unpredictable.
No one can predict crypto progress accurately.
I also ever sold my tokens before market up.
When market up, there is panic.
Panic selling because fear, market will go down.
