Bitcoin’s mining difficulty fell about 7.7% on March 20, lowering the metric to 133.79 trillion at block 941,472 and easing conditions for miners that remain online. The reset followed slower block production over the prior 2,016 blocks, with average block times around 12 minutes 36 seconds. Listed miners are also increasingly shifting capacity toward AI and high-performance computing as competition for power and data-center resources grows.

Bitcoin saw another failed upside attempt over the past week, meeting strong resistance at $75,000 before sliding back toward $70,000. Glassnode said options traders are leaning more defensive, with greater demand for downside protection alongside lower volatility expectations. Bitcoin was last noted at $70,668, up 0.33% on the day, while daily volume fell 17.30% to $36.67 billion.

On March 21, 2026, Bitcoin hovered around the $70K level after a late-February selloff tied to U.S.-Iran tensions and a subsequent rebound of more than 10% from the lows. March ETF activity stayed volatile, with a -$349 million combined outflow reported for March 6, while select inflow days favored BlackRock's IBIT. Technically, BTC retook the 50-day SMA as RSI and MACD shifted toward a more constructive setup, while $65K was highlighted by a trader as a key downside marker.

James Wynn has returned to Hyperliquid after previously turning $4 million into $87 million and later losing nearly all of it. He deposited $3,911 from referral rewards and opened a 40x short on 2.69 BTC, with liquidation at $71,112.48 while Bitcoin traded around $70,697. The trade sits about $415 from liquidation, drawing fresh criticism from other crypto traders.

Bitcoin held above $70,000 for the first time in nearly two months over the past week, but market nerves rose on Friday, March 20 amid expectations of possible US Federal Reserve rate hikes. An on-chain view argues BTC could still slide below $50,000, with analyst Ali Martinez pointing to an MVRV-based downside target around $43,000. At the time of writing, BTC traded near $70,477, up 0.6% in 24 hours.

Bitcoin’s move during the US-Iran conflict has resembled its first-month reaction after Russia’s February 24, 2022 invasion of Ukraine: a sharp sell-off, a quick rebound, then choppy consolidation. After US and Israeli strikes against Iran that began around February 28, 2026, BTC recovered back into the $70,000–$73,000 range in the following weeks. RSI, CMF and price action collectively point to dip buying and volatile range trading rather than a sustained breakdown so far.

On March 21, 2026, analyst Benjamin Cowen said Bitcoin remains in a bearish market structure despite a March rally. He pointed to prior bear markets where BTC made February lows (2014, 2018, 2022, and 2026) and argued the trend would only improve with a convincing close above $83,000. Cowen also warned a lower-high setup could be followed by a selloff into a lower low.

Bitcoin hovered around $69,800 as a record $7.1 trillion notional options expiry hit markets, with roughly $5 trillion tied to the S&P 500 and $880 billion to single stocks. Crypto sentiment was weak heading into Friday, with the Fear and Greed Index at 30 after a recent low of 23. The week’s event risk also includes $13.5 billion in crypto derivatives expiring on Deribit on March 27 and recent spot Bitcoin ETF outflows led by IBIT and FBTC.
