Well, some whale lost his patience, so what? May be he is an early adopter, or may be he bought at 18K-ish and now is furious he lost so much   The price will recover sooner or later. I am still determined to start selling for a house at 40K-ish price. And I will hold 2/3 BTC's until I retire. I don't care if the 2014-2015 scenario will repeat or not. Btw, there are 3 differences:
In 2015:
1.  most of the people didn't know about bitcoin, let alone buying it. Now most of the people know and are thinking about buying. May be they are waiting for a good price or LN  
2.  no hope for Institutional investments. Now Coinbase, Van Eck Associates Corp., SolidX, Goldman and Sachs are ready to start deals.
3.  miners were still very profitable, while now they are on the edge. As from today all home miners in countries with electricity price >0.14$ lost their profit. Soon the rest will follow. Usually this means a coordinated attack to pump the price. We'll see...
