At this moment the bitcoin price has massively fallen, so what's can bitcoin holders do! Do the required to sell their bitcoins or waiting it till the price of bitcoin get recovery?.
the right time to sell is when the price is higher around 9000$ you should sell it before the price fallen.
As of now if you do not want to lose you just need to hold your coins or else you can also do short trade.
Selling it right now is not the best option this only means you will accept the lost selling it.
But its depend if you need the money today then you dont have any other choice than to sell it.
