What makes people compel to hold the bitcoin in this critical situation? What are they waiting for? Any good reason?
Since it's the very first digital currency being launched hence everyone feels that it has the cpacity to go beyond 3k+$, something which is even proposed by Goldmann Sachs.
$3k+ is real in couple of weeks and we'll see maybe Bitcoin goes even much higher. Today's drop is created artificially by whales to buy more at the lowest price possible. If I was a whale I'd do the same, so I don't blame them for dumping. What is a really stupid thing to do is panic selling your coins now when the price is low. If you are not a whale, but just an average holder, do not do it, because later you will be able to buy only a fraction of what you sold for the same money.
