I think he is not panic now, BTC is already moving uptrend again, it has reached $11K easily and now, it seems it's gonna break $12K soon.
OP should make a good decision this time, when BTC reached $13,000 again, he will be on profit, so I hope he should not be greedy.
Bitcoin moves up and down. I won't rule out the days Bitcoin will be again lower than the price he paid for it. And then he will have this "problem" again.
Depending on the funds available and the "balls", people panic easier or harder.
Since OP panicked this easy, I'd say he'll do that again, sooner or later.Of course greed is bigger than brain and he will not sell now he sees he can have profit.
However,
it's his money, his choices.because of this, we can only give advice. because basically, no one forced him to buy bitcoin at the time. Well, for now, waiting is the best way to get things back. I suggest to resell when your assets have returned to normal, because you already know that no one knows when the price of bitcoin will go up, and down. if you can't deal with the risk, it's better to sell when you feel you have a profit, or sell it before a worse loss.
