There’s no single lowest profitable hashrate for Bitcoin mining; profitability depends on your electricity cost, hardware efficiency, Bitcoin price, network difficulty, and pool fees, but modern ASICs offer better chances, with even lower-end efficient models like Antminer S21 (200 TH/s) potentially profitable if power is cheap, while very old miners struggle against high network difficulty. A very small hashrate (e.g., a few TH/s) will likely take decades to earn a single Bitcoin, but newer, more efficient machines at higher speeds (100+ TH/s) have a better shot, especially with rising hashprice.
