I added the Bitcoin price in Swiss franc.
I have a question, or maybe I noticed one bug on your website.
When I open it, page loads and it shows current market value of Bitcoin in USD with chart, but when I switch to any other currency (eur, chf, pound, etc) or when I click back to USD, there is no more chart.
If I want to get back chart I need to click below on buttons for 1D, 1W, 1M, etc.
Maybe this is made by design, but I would like to see automatic loading of charts with all currencies.
I tried to re-produce the bug and found an issue with Firefox when the referrer headers are disabled in-combination with Chart.js.
