In BTC/USDT, which is the quote currency?
The same coin may have slightly different prices when quoted in different currencies. When the price gap gets large, arbitrage traders step in and bring prices back into line. Common quote currencies include stablecoins such as USDT, USDC, and FDUSD, as well as trading markets quoted in BTC or BNB.
Liquidity varies across trading pairs. Buying or selling the same coin in a more active pair generally results in less slippage.
For a real-time reference: $BTC quotes 76037 (24h +0.22%).
