Today is also all red, with -9% drop for the day which is a lot. I understand coins go up and down but when almost all of them go down, it's not a good sign.
Some of them might drop up to -20% but still people are patiently waiting for it to rise up again. This event is just normal as per no events or FUD that is going on and this is how the market works. You shouldn't expect more or less because it is so unpredictable, if you thought that they will go down by the next day then the market suddenly changed and it rose up before you manage to do something about it. That's how the market works.
