Blockfolio is well known for tracking many cryptocurrencies and altcoins and you can add your coins and just monitor your assets from there. Honestly, I've heard about it before but haven't tried. They've announced that they are starting trading in their platform soon so it's expected that they will airdrop tokens (Not Confirmed) but the user who have or will join may earn crypto free by just putting their email pre-register.
