Bitcoin miners, including Riot Platforms and MARA Holdings, have accelerated the sale of their Bitcoin reserves due to rising operational costs and declining profitability. Riot Platforms sold 3,778 Bitcoin in the first quarter at an average price of $76,626, generating $289.5 million, while MARA Holdings liquidated 15,133 Bitcoin for approximately $1.1 billion. These sales were driven by increased energy costs and reduced mining margins following the recent halving cycle.The industry-wide sell-off reflects a strategic shift as miners face tighter breakeven thresholds. Rising energy prices, exacerbated by geopolitical tensions, have forced miners to convert reserves into liquidity. This trend has led to a reduction in mining difficulty and hash rate, as less efficient operators shut down. Meanwhile, companies like MARA are diversifying into artificial intelligence and energy infrastructure to stabilize revenue streams amid changing market conditions.
