Spot pairs
Number of active spot pairs, reflecting the diversity of trading opportunities.
Counts the number of pairs available for spot trading.
Spot refers to cryptocurrencies that can actually be purchased, as opposed to derivatives that purely reflect the price.
The more pairs there are, the more accessible and liquid the cryptocurrency is. A cryptocurrency listed on only one exchange remains fragile.
Also check the quality of the exchanges (see the trust score on https://www.coingecko.com/en/exchanges) and not just the quantity.
