Hello, why everyone is so afraid of crypto market falling again? I think this 1000$ bitcoin growth is the new beginning of rapid growth of all crypto market! Guys dont be so depressive, stop panicking and selling just relax and bitcoin is going to reach 20000$ in summer! 
We have different perspective and that is good because when there are some weak hands then there are some strong hands too. That is the reason why the price was easy to change because of too many holders and panic sellers. If everybody do hold then we can see the fastest increasing of price but you cannot gain more and trading can have less profit but if the price was volatile then traders can get more profit.
