yes, and i am watching that pricing every day with a widget to haceve realtime refresh. i don't sure if there is a reason for me, despite i don't hold any bitcoins yet, it has something to do to me, i believe that is when to buy it.
For myself, I don't, but I can say that I am updated, but not on an everyday basis. Maybe two or three days interval, but sometimes, when the prices are going haywire, changing in mere seconds, I check it to update myself what's affecting such quick changes. However, I won't say it's bad to check it everyday, I mean, it can help you be updated, and it can dictate the moves you would do in order to make good deals whether your are trading or investing.
