JPMorgan Chase reports a 3% decline in the average monthly computing power of the Bitcoin network in June, attributed to a heat wave impacting mining operations. Despite this, Bitcoin mining profitability has improved, with miners earning an average daily block reward income of $55,300 per EH/s, marking a 7% increase from April. Additionally, the daily block reward gross profit rose by 13% month-on-month, reaching its highest level since January. The total market value of 13 US-listed Bitcoin mining companies tracked by JPMorgan increased by 23% to approximately $5.3 billion.
