Hi, I find very usefull the BTC button, to have an option of viewing all prices in terms of bitcoin. Right now the "% Change (24h)" column is calculated with respect to USD price. Thus when see prices in USD or I see them in BTC, I see the same number in % change. I think this is not the good way. In BTC price mode the bitcoin % change, should be always 0% and other altcoins % changes should be calculation with respect to bitcoin price. What do you think?
