Hi, I'd like to start by saying I absolutely love coinmarketcap.com, and use it constantly.  But one feature on the most recent update that is really frustrating me, and is in fact why I made my account on the forums.  It's the price being changed to BTC on the graphs, without the option to change it to USD, I used that multiple times a day to check what a coin use to be worth X amount of time ago.  But now I have to know what BTC is worth and do the math etc. before i can find out what a coin was worth X amount of time ago.  I am quite excited to see the 365 day button though.  I would just love to see a toggle button for USD/BTC on the price side of the graphs.  I do hope you see this post, and greatly appreciate your effort on an awesome site.  Thanks for reading this, and keep up the good work.
