Upbit

Upbit is a centralised exchange that has been operating since 2017, registered in South Korea. CoinGecko tracks 351 assets across 619 trading pairs here. Its trust score is 8 out of 10, ranking it 26th of the exchanges CoinGecko scores. That score blends order book depth, bid-ask spreads, reported volume against web traffic, and whether the venue holds recognised licences — it is a liquidity and transparency measure, not an audit or a safety rating.

Across the 100 busiest pairs on this venue, 66.7% of the volume runs through just three of them — XRP/KRW, TRUMP/KRW and USDT/KRW. Volume is spread across enough markets that the smaller pairs are still worth checking individually rather than assuming they inherit the exchange's overall liquidity.

The median bid-ask spread on these pairs is 0.304%. That is a workable spread for retail-sized orders, though it is worth checking the individual pair you intend to trade rather than relying on the median.

By quote currency, 0.0% of this volume is priced in stablecoins and 100.0% in government currencies. A venue with that much fiat volume is generally usable as an on-ramp: you can move money in from a bank rather than arriving with crypto already in hand.

One caveat about the volume figures on this page: 37,872 BTC of 24-hour volume is what Upbit reports, not an independently measured number. Reported volume and real volume are not always the same thing across the industry, which is precisely why the trust score exists. Custody is a separate question again — where the exchange holds your coins, under which jurisdiction, and what happens if it fails are not captured by any of the figures above.
