They aren’t the only ones to leave recently. Last week, CryptoX broke the news that Chief Operating Officer Samir Shah, a 12-year JPMorgan Chase veteran, abruptly left Pantera after barely two months on the job. Legal counsel Joe Cisewski left to become chief of staff for Christy Goldsmith Romero, a commissioner at the Commodity Futures Trading Commission, and Brian Flaherty, a finance manager, left in May after just over a year at Pantera, according to his LinkedIn page.
