It doesn't support the price of many cryptocurrencies. It's limited to very few cryptocurrencies I guess; BTC, ETH, LTC & a few more. I tried this earlier to keep track of my portfolio performance but due to limitations, I couldn't use it as I had few altcoins as well (small investment though LOL). I tried another method as well but unfortunately, I failed to fetch data in the spreadsheet. I'm using coinmarketcap for now.
