Bitcoin, ether, and dogecoin all held steady as U.S. President Donald Trump sets a deadline for Iran to agree to a deal, threatening to destroy "every bridge in Iran" if it does not. The largest cryptocurrency is down 0.6% over 24 hours after a potential 45-day ceasefire briefly boosted prices. Ether fell 1% to $2,104, solana's $79.75, XRP lost 1.6%, and BNB held relatively flat at $598. Both Bitcoin and the S&P 500 posted their longest advance since January.
