According to Odaily Planet Daily, research and brokerage firm Bernstein rated Riot Platforms, CleanSpark, IREN and Core Scientific as "outperforming" in its Bitcoin mining report, while Marathon Digital was rated "market performance."
The evaluation is based on five key indicators: production and computing power, operation and energy efficiency, electricity, computing power cost and artificial intelligence strategy. Core Scientific leads in computing power cost and AI strategy, while CleanSpark and IREN excel in energy efficiency.
Although Riot lags behind in production and efficiency, it makes up for it through electricity points and improved production efficiency. Marathon has improved its operating efficiency by switching to a self-operated mining model.
