Let's talk about market cap and trading volume.
24-hour trading volume is the total value of trades over the past 24 hours, reflecting how active trading has been during that period.
To be honest, I only learned this later: when looking at trading volume, first check the measurement basis. Don't compare 24-hour trading volume with the volume of a single candlestick.
By the way: $BTC current price 82882.98 (24h +0.13%).
