The total cryptocurrency market cap recovered from a crash. The total market cap increased from $90 billion to $100 billion. 
The strange thing is that when you check the math with the 24 hr volume. It doesn't quite add up.
I am not market expert but it is counter intuitive for the market cap to increase by more than the amount of money traded in it. This just must be the whole supply and demand mumbo jumbo people talk about. It is fascinating to see that confidence in a market from people buying when prices drop too low can cause it rebound so much. But this is why I only mine currency it makes a little more sense to me.
