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?.
What does the bitcoin holders do? Then probably the main thing they need to do is to just hold for their coins and wait for the recovery of the market and don't panic at all times because this was the problem if you become panic. Become relax at all times remember always that in the cryptocurrency there is no exact value it is always a volatile so just wait and probably the pump of the market will officially occur again.
