I would like to explain to you how and where to create a free real-time portfolio. all coins listed at https://coinmarketcap.com are listed there. A portfolio that immediately indicates the current price changes is very important if you are cryptotrader.
But also for non-traders it can be very useful.
You have immediately all the coins you own at a glance. The value of the different coins can be displayed in close to all usual currencies. (USD / EUR / GBP and so on, but also in BTC / ETH and more!)
