Top Bitcoin news now:
- ETF flows just flipped stronger again. CoinShares’ latest data shows $1.03 billion of weekly inflows into digital-asset investment products and $790 million specifically into Bitcoin as of March 30, while Investors Business Daily reported that U.S. spot Bitcoin ETFs posted a $1.32 billion rebound in March, ending a four-month outflow streak.
- Strategy hit pause on buying Bitcoin this week. A fresh SEC filing says Strategy bought no bitcoin during March 23–29, 2026 and still held about 762,099 BTC as of March 29, with an average purchase price of roughly $75,694.
- Quantum risk is suddenly a major headline. Google Research published a March 31 post on responsibly disclosing quantum vulnerabilities in crypto, and coverage from WSJ and MarketWatch says the new work suggests future quantum attacks on exposed Bitcoin public keys may require far fewer resources than previously estimated. This is not an immediate break of Bitcoin today, but it is the biggest longer-term security story hitting the market right now.
- Bitcoin mining economics are getting uglier. CoinDesk reported Bitcoin’s network hashrate just posted its first quarterly decline in years as some miners pivot capital toward AI infrastructure, and Barron’s reported MARA sold about $1.1 billion of bitcoin to fund AI expansion and debt repurchases.
- Institutional crypto is still maturing through public markets. CoinShares said its merger transaction became effective on March 31, 2026, and IBD highlighted the Nasdaq debut tied to that SPAC combination as another sign that crypto finance is continuing to integrate with traditional capital markets.
Read on the tape: the immediate driver looks like a mix of macro risk relief and renewed ETF demand, while the bigger structural stories are quantum-security prep, miner stress, and continued institutionalization.
