I was looking for portfolio management apps when I stumbled upon altpocket.io
I'm not going to bore y'all by telling you all the features of the website. The user interface is pretty straight forward.
The difference between other portfolio management apps is that here you can simply get your API keys from Bittrex or Poloniex and all the orders will automatically get registered on your profile.
They support all coins from Coinmarketcap, Bittrex and Poloniex.
It keeps track of your investments in such a way that it shows you how much you bought the coin for and how much profits you made with a single investment or your entire portfolio.
These are the things which stand out from other portfolio management apps/websites I've read about.
Hope you guys use this website. If you do like the website, you can donate them by clicking "Support Us" on the left side menu.
