According to BlockBeats, CryptoQuant analyst Axel has observed a significant decrease in the weekly trading volume of the BTC/USD pair on centralized exchanges following the LUNA collapse. The volume has dropped from a peak of 2.9 million in July 2022 to 426,000 in the most recent trading session. This reduction in available supply on trading platforms could potentially exert upward pressure on Bitcoin prices, suggesting a long-term bullish signal.
