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.
