Inverted pairs are “synthetic pairs” and inversions of naturally occurring trade pairs. For example, this page currently displays the BTC/RVN pair. This trading pair (with Bitcoin as the base currency and RavenCoin as the quote currency) does not exist on any exchanges listed by us. But the un-inverted version of this trading pair (i.e. RVN/BTC) does exist on one or more cryptocurrency exchanges. You may click here if you’d like to un-invert this pair.
