If this year is red then this is completely unsurprising, after a sharp increase, a sharp pullback, this is a common phenomenon in the market of crypto-currency
So true mate this is a common happening to the market or it was not new so we should always expect this ,but never give up that easy with our coins if it is not really needed. Also if you see that holding it for long term can give you more profit then don't sell it. I just want to reverse what you are saying mate that after a sharp pull back there is a sharp increase also and vice versa.
