Wall Street analysts expect a further slowdown in trading volume for Coinbase in the third quarter, triggered by a lack of catalysts and an uncertain regulatory environment. Coinbase is set to report earnings post-market on Wednesday. Analysts predict revenue could be down 13% this quarter, with spot trading drying up and the usual catalysts not kicking in. The U.S. regulatory clouds are not clearing up, contributing to the anticipated decline. ETH slumps further adding to the negative outlook.
