Bitcoin (BTC) futures daily trading volume plunged sharply from about $20 billion on June 11 to about $5 billion on June 13. This is a negative sign because the volume increased during the sharp fall on June 11 but reduced during the rebound on June 12 and 13.
On June 14, the top-ranked cryptocurrency on CoinMarketCap declined but the futures volume picked up, suggesting a higher number of bearish trades on market declines and a lesser number of bullish trades during pullbacks.
