On 28 March 2026, Sen. Elizabeth Warren pressed the U.S. Commerce Department for records on how it is addressing what she described as potential national security risks tied to Bitmain. The concerns referenced include whether China-linked remote access could enable espionage or power-grid disruption, alongside Bitmain's outsized role in mining hardware supply and recent large U.S. purchases of its rigs.

Bitcoin fell to $65,548 before trading near $66,338, down 3.3% on the day, alongside heavy downside volatility. Liquidations reached $183 million, including $170 million in long positions, while on-chain trackers noted whales leaning into short exposure. Derivatives flows and momentum readings stayed negative, leaving $65k in focus, with $63,400 cited as a potential next level if selling persists.

Bitcoin continued to edge lower as traders rebuilt derivatives exposure while spot demand weakened. Analysts cited three consecutive days of BTC moving back onto exchanges, rising open interest, and a return to negative funding as signs of cautious positioning. They also pointed to a deeper negative Coinbase Premium versus a positive Korea Premium as evidence of regional demand divergence.

An Arkham report released Saturday, March 28, ranked Satoshi Nakamoto as the largest Bitcoin holder at about 1.1 million BTC worth over $77 billion, while Coinbase appeared second with roughly 982,000 BTC. The same data set showed Strategy with 738,000 BTC in total, including about 443,000 BTC visible on-chain. Commentators said Coinbase’s figure reflects user custody rather than corporate holdings, unlike Strategy’s treasury position.

Bitcoin slid to $65,498 on Friday, its lowest level since March 2, after the year's biggest options expiry and continued outflows from crypto ETFs.

Bitcoin posted a nearly 25% drawdown in Q1, as macro volatility intensified and markets leaned toward tighter U.S. monetary policy. Rate expectations shifted toward potential hikes into 2027, while sentiment weakened and short-term holders sent about 21,700 BTC to exchanges in the past 24 hours at a loss. The mix of falling risk appetite and muted institutional demand is raising questions about whether the pullback is turning into a broader bearish phase.

Morgan Stanley has filed with the U.S. Securities and Exchange Commission for a spot Bitcoin ETF that would charge a 0.14% expense ratio. The proposed 14-basis-point fee is below Grayscale's 0.15% Bitcoin Mini Trust and BlackRock's iShares Bitcoin Trust at 0.25%. The move highlights intensifying cost competition as issuers look to attract both institutional and retail flows.

A weekly roundup highlighted heightened cross-market volatility and fresh signs of traditional finance embracing digital assets, including Goldman Sachs pointing to a potential cyclical bottom for crypto.
