There is no perfect Entrance and there is no perfect Exit from a position in crypto!
When you're buying, of course, the price could decrease in the short term. You don't need to panic.
The same goes for selling, you sell, and suddenly you see the price increasing.
Now you're starting to doubt yourself, that you weren't patient enough to wait, but it's a lie...
You have done everything alright, but your perception of yourself and time was wrong.
Don't blame yourself for nothing.
You have done everything alright. Additionally, you were responsible enough to take profits and not be greedy and delusional.
You are great. Believe in yourself.
Shalom.
