Since I am a bitcoin and altcoins traders and most of the exchangers platforms do display the list of there coins in terms of Btc. I do get confused especially when I started to trade as I will look at a cpin performance in terms of dollars and see it doing well and after changing to bitcoin at hittps://coinmarketcap.com.  I will see the same coin performance poorly because of bitcoin increasing. However, those that trading with USD and cryptocurrencies you have to always view your assets in terms of USD.
