Riot Platforms Shifts 500 BTC to NYDIG Custody as Miners Rebalance Bitcoin Treasuries

Riot Platforms has transferred 500 Bitcoin—about $30.7 million—to NYDIG Custody, according to on-chain tracking data from Arkham. The move has fueled market chatter about a possible selloff, though the transfer itself does not confirm any BTC has been sold. A clearer signal would emerge if the coins later move from NYDIG to a crypto exchange or an OTC trading desk. If the BTC remains in custody, the transfer may simply reflect routine treasury operations—positioning assets for liquidity needs, adjusting custody arrangements, or preparing collateral for financing. Miner treasury reshuffling is already visible in reported reserve figures. BitcoinTreasuries.NET data show Riot held 19,368 BTC at the end of 2025, but after sales in January and April 2026, its holdings stand at 15,680 BTC. The adjustment comes as the company recently posted record revenue of $647.4 million, up 72% from $376.7 million in 2024. Other miners have also reduced BTC balances. Hut 8 Mining Corp. held 10,667 BTC in November 2025 and was reported at 10,278 BTC at press time. Mara Holdings, Inc. held 53,822 BTC in February 2026, declining to 36,303 BTC. Core Scientific finished 2025 with 2,537 BTC and is now at 547 BTC. The broader backdrop is a shift in mining economics through 2026. CryptoQuant data tracking Bitcoin price, hashrate drawdown, mining difficulty, and network hashrate from July 2025 to July 2026 show why financial pressure has increased and why some public miners have moved or liquidated portions of their BTC. Mining profitability surged in the second half of 2025, driving network hashrate from roughly 850 EH/s to above 1.08 ZH/s. Conditions tightened in 2026: by February, Bitcoin fell from above $120,000 to nearly $65,000, while elevated hashrate and rising difficulty intensified the traditional "mining squeeze." Less efficient operators began powering down as margins deteriorated. With hashrate down about 15% from peak levels and profitability under sustained pressure, miners with stronger balance sheets have increasingly managed reserves actively rather than holding all newly mined coins. As rigs are shut down or operations scaled back, network hashrate has eased from above 1.08 ZH/s to about 930–950 EH/s. In that context, Riot's 500 BTC transfer to NYDIG Custody aligns with broader industry behavior. Final takeaway: The custody transfer alone does not confirm a selloff, but Riot's BTC holdings have declined from 19,368 to 15,680 BTC. In 2026, the combined impact of Bitcoin's price swing, hashrate drawdown, higher mining difficulty, and shifting network hashrate has pushed miners to recalibrate their Bitcoin treasuries.
