0719 GMT - Bitcoin rises modestly following gains on Wall Street overnight driven by a rally in tech stocks. Investors buying shares of companies tied to artificial intelligence boosted tech stocks, leading U.S. stock indices higher. An easing of oil prices is also supporting risk sentiment. Lower oil prices reflect some profit taking and reports that Saudi Arabia could soon restore some flows through its damaged East-West pipeline which was closed after a drone attack from Iraq. Bitcoin rises 1.1% to $77,392, LSEG data show.
