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.
no need to regret that what you did at that time was more important than you when it came to holding your bitcoins. everyone has a problem sometimes you have to make a priority scale, if at that time you don't sell, can you solve your problem.?
sustenance will certainly have time again, try to be able to return to catch up if there is still time if you intend to, because the price will continue to increase.
