I usually dont check the value of the bitcoins i do have, because when i log in into poloniex i got the worth of the day, but i dont check it at all i do use those menu to deposits and cashouts, but i do see the value, all i care now is to get bitcoin since i do pretend to make one last project and then start saving bitcoins for a better price or a possible need into the future.
There is no need to check the bitcoin price daily. It is very volatile. But the long term trend is up now.
For me its still good to monitor bitcoin price if you are holding bitcoins for a long time you dont need to monitor it to know the price daily but for some traders they needed it because they are buying low bitcoins and sell high depends of their margin..
