Riddle me this.If you've had this problem "since i signed up on sr.", then how did you know it used to be there?...It was removed after a security audit of the site, apparently. As theammoman noted above, there's lots of places the exchange rate is available.Additionally, you can go to your settings page and view the main site in either BTC or US$. Set it to BTC and you'll know exactly how much BTC you'll currently need. 8)
