May 2 (Reuters) - Coinbase Global posted a sizable jump in profit in the first-quarter, helped by an uptick in cryptocurrency trading following the launch of the first U.S. spot bitcoin exchange-traded funds in January.

The company on Thursday reported a net income of $1.2 billion in the three months ended March 31, compared with a loss of $79 million or $0.34 per share a year ago. (Reporting by Hannah Lang in New York Editing by Chris Reese)
