SINGAPORE — Bitcoin surged to a two-week high on Monday after the attempted assassination of US presidential candidate Donald Trump raised the odds of the former president, who has presented himself as a champion of cryptocurrency, winning the upcoming election.

Trump said he was shot in the ear during the attack at a rally in Pennsylvania on Saturday. His campaign said he was doing well. Some investors said the attack bolstered his chances of winning back the White House, and trades betting on his victory are expected to increase this week.
