That was very bad time for me, when i sold out my Bitcoin. When bitcoin price was 9k+ usd, then i sold out my all Holding Satoshi for my personal problem. But now current price of per Bitcoin is 41k+ usd.
What was the reason for your withdrawal when it was $9k? It is disappointing to see the rise after we've sold. But if you have the best reason for selling by that time and you truly need it, don't have to feel bad for that sale. You have used it very well and you have solved that problem by selling at that time. Honestly, you'll see too many people that have sold earlier but why you haven't thought of remaining even 10%-20% of your total holds?
