(Reuters) -U.S. cryptocurrency exchange Coinbase Global Inc on Tuesday beat market estimates for second-quarter profit boosted by a near 38% jump in trading volumes on a sequential basis, but forecast a drop in current-quarter volumes. Coinbase, which has benefited from the growing adoption of digital assets, said the reported quarter illustrated the volatility of the still nascent sector that faces calls for more regulation. Chief Financial Officer Alesia Haas said Coinbase is paying close attention to the U.S. Securities and Exchange Commission (SEC) Chair Gary Gensler’s comments, who called on Congress last week seeking more authority to better police cryptocurrency trading, lending and platforms. “We’re eager to understand the legal framework for the concerns that he has raised and how any of those may impact our product roadmap,” Haas said in a post-earnings conference call with analysts. The exchange also plans to grow the number of assets listed on its platform, with Chief Executive Officer Brian Armstrong stating that he wants Coinbase to be the “Amazon of assets” and list every legal crypto asset on its platform. For the quarter ended June 30, the company’s trading volumes rose to $462 billion, from $335 billion in the quarter ended March. Bitcoin trades comprised 24% of Coinbase’s trading volumes for the quarter, down from 39% in the first quarter. However, for the third quarter, it expects trading volumes to be lower than the second quarter, as August month-to-date volumes have improved compared to July, but remain lower than what was seen earlier in the year. On an adjusted basis, the crypto exchange earned $3.45 per share. Analysts were expecting a profit of $2.33 per share, according to IBES data from Refinitiv. Coinbase, one of the largest cryptocurrency exchanges in the world, went public through a direct listing in April..
