Tuesday got off to a strong start: Bitcoin extended its bullish momentum, hitting $80,000, while the three major U.S. stock indexes traded mixed.

US Treasury Secretary Scott Bessent announced on Monday local time that the United States will launch a new sanctions operation dubbed "Operation Economic Outcast" to further cut Iran off from the global economic system, warning countries and enterprises that continue to conduct business with Iran will face US sanctions risks. The move comes as the conflict between the US and Iran has dragged on for nearly six months. The US had previously pressured Iran via military operations and long-term economic sanctions, but the two sides have not reached an agreement on fully reopening the Strait of Hormuz and restricting Iran's nuclear program. According to market data from BIT (bit.com), US stocks closed on Monday: the Dow Jones Industrial Average rose 0.26%, the S&P 500 fell 0.28%, and the Nasdaq Composite dropped 0.76%. SK Hynix (SKHY.O) slid 4.9%, Micron Technology (MU.O) fell 5.8%, SanDisk (SNDK.O) dropped 6.4%, while Nvidia (NVDA.O) and Intel (INTC.O) each declined 3%. Per HTX market data, Bitcoin hit $80,000 again overnight for the first time in 101 days, surging nearly 30% in a week. It is now trading at $77,898, with a 1.25% 24-hour gain.
