Cryptocurrency executives swilled cocktails and danced to rap superstar Snoop Dogg on Friday night as they celebrated the approaching inauguration of President-elect Donald Trump, whose administration has promised major changes in crypto policy. After years of butting heads with Washington policymakers, executives from crypto companies including Crypto.com, Kraken, and Exodus partied at the first-ever crypto inauguration ball held at the 90-year-old Andrew W. Mellon Auditorium beneath towering 62-foot (19-metre) columns. Clad in black tie and ball gowns, guests noshed on miniature lobster rolls and Trump's favored McDonald's burgers and fries, according to social media posts and two attendees who spoke to Reuters.
