Bitcoin climbed back to $77,356 over the weekend, posting a modest 0.68% gain, after Donald Trump announced a U.S.–Iran nuclear agreement had been "largely negotiated" — a signal that sent a ripple of optimism through risk assets broadly. Ethereum slipped 0.73% to $2,107, while total crypto market cap held at $2.66 trillion. BTC dominance ticked up to 58.3%, and the Fear & Greed Index sat at 30, still firmly in Fear territory.
On the regulatory front, the SEC approved Nasdaq Bitcoin Index Options on PHLX, and Grayscale filed a third amendment advancing its proposed HYPE ETF — two incremental steps toward broader institutional product access. On the downside, two stablecoins suffered exploits and lost their pegs to the dollar and euro respectively, a reminder that systemic risk in the stablecoin layer remains live.
