These three we ask ourselves, every five minutes, and keep every answer with the time it was given. The list above is what the exchangers publish about themselves.

What you receive is computed from the exchanger’s own rate and its own declared fees, for the amount you entered — not from a market average. “Clean on our feeds” means the site appears in none of our threat sources; it is the result of a check, not a recommendation. We are not paid by the exchangers listed here.
