Crypto exchange rates
FXRate.io starts with Bitcoin for the international USD site and can be expanded to more crypto assets when the data feed is enabled.
How crypto rates differ from FX
Traditional foreign exchange is anchored by central banks, commercial banks and global payment flows. Crypto prices are set by digital-asset exchanges and can vary by venue, liquidity and custody method.
For now, FXRate.io focuses on Bitcoin because it is the most widely recognized crypto reference pair for international USD users.
