Simple answer:- speculators. The smart ones know that the price is determined solely by sentiment, which comes in waves.who is increasing their bitcoin holdings now and why? Why hasn't it crashed deeper?
For one reason or another the sentiment may turn sour and people sell, causing the price to drop even more as panic sets in. A clever 'investor' watches this wave develop and buys when it is close to the trough. As the 'bear' wave ends sentiment turns positive and the price increases, causing others to join in for fear of missing out. Of course this doesn't last either, so the cycle repeats.
An experienced 'investor' knows that the price is driven by people's emotions, so he isn't just watching the price. He's also looking at volume, reading news reports, and checking social media to see where the sentiment is going. A big investor can also manipulate sentiment with well timed announcements and large transactions.
Day to day prices jump up and down 'randomly', so buying and selling on the spot price is just gambling. But over a longer period the waves become predictable. Bitcoin currently has one wave with a period of about 1 week, and another of about 2 months. A smart 'investor' can make consistent money by synchronizing his transactions to these waves. The only problem is that the tide is going out, so the waves are getting smaller. Eventually they may become so weak that 'investing' in bitcoin is not profitable enough.
One reason Bitcoin hasn't crashed completely is that professional speculators are still getting enough out of the game to stay in it. When will it end? Perhaps never. It all depends on how long they can keep the waves of sentiment going. But so far Bitcoin has followed the typical behavior of a bubble, and with no fundamentals to give it real value there is no reason to believe it won't continue down that path.
