It is not only day traders who spend their day watching the chart, there are hodlers with a lot of bitcoins who cannot take their eyes of the charts because they are worried of its movements, funny thing is that many of them are not even ready to sell irrespective of what happens. I remember when i was new to the network and had my first bitcoin, i used to be like that, looking at the price and what is happening, glad i stopped that and i am more confident right now.
