最新报道:Bitcoin mining profitability has surged as ASIC miners become more efficient amid a 20% price rally for BTC. With Bitcoin trading above $43,000, top-tier mining rigs like the Bitmain Antminer S19 XP are generating daily revenues of $15-$20 at current electricity costs. Analysts note that even older models like the S19j Pro remain profitable if power expenses stay below $0.07/kWh. The mining difficulty adjustment expected this week could further improve margins for well-capitalized operations. However, experts caution that smaller miners may still struggle due to high operational costs and the upcoming Bitcoin halving event in April 2024, which will cut block rewards by 50%.
