For the current price now there is doubt that there is a crash coming because the price is way too far from the price before and if the hodlers will see that the price is getting a bit low then they will join that and dump their coins and make a dip. Just be ready for some worst case scenario and don't hesitate to sell or take your ROI before hodling it.
I think if a Bitcoin go up sharply then it can easily go down , so indirectly it is just like at the condition when go down then it will surely be called crash of the Bitcoin in the Bitcoin market .
well here I don't think so that it's price will go at any lower price of 800$ per Bitcoin .
