On March 23, Bitcoin’s mining difficulty dropped by approximately 7.76% to 133.79T—marking the second-largest negative adjustment of 2026 so far. The network’s current hashrate has fallen to roughly 903–948 EH/s, a significant drop from its 2025 peak. Analysts note that with bitcoin prices below production costs and mining revenues under pressure, many miners are shifting their infrastructure to AI and high-performance computing (HPC) operations, driving structural transformation in the industry. Mining firms such as Core Scientific and Bitdeer have accelerated these shifts, which could impact the Bitcoin network’s long-term security and hashrate distribution.

On March 23, NYSE Arca and NYSE American—units of the New York Stock Exchange—fully lifted position limits and exercise restrictions on 25,000 crypto ETF options contracts, a move that means all major U.S. options exchanges have now uniformly relaxed the related restrictions. This change applies to 11 Bitcoin and Ethereum spot ETFs, including the iShares Bitcoin Trust and Wise Origin Bitcoin Fund, enabling FLEX options trading for these funds. With the new rules in effect, crypto ETF options will align with the same standards as other commodity ETF options, and position limits can rise to more than 250,000 contracts depending on liquidity. Analysts say this step will greatly boost institutional operational flexibility for hedging, arbitrage, and structured products, further advancing crypto assets’ integration into the mainstream financial system.
