I'm always checking Bitcoin prices throughout the day, and this Paybis bitcoin calculator has become my favorite shortcut. You just type in how much BTC you want to buy (or how much fiat you want to spend), and it instantly shows you the conversion in 45+ currencies. It also has a profit calculator where you can pick any start and end date to see how your investment would have performed. Super useful for planning buys or just satisfying your curiosity. Bookmark it and thank me later.
