Its not easy to keep an eye on all the coins you have in your portfolio even some coins has not been listed
yet we invest in but I use blockfolio app for all the listed coins. With the help of blockfolio app I am updated myself most of the time but many coins are not available on blockfolio app So I maintained an excel sheet as well. Daily in the morning my first work is to check market value of my all coins that way I stay informed on daily basis or I check market on coinmarket website also.
