Michael Sonnenshein, Grayscale Investments' CEO, is stepping down after a decade, with Goldman Sachs' Peter Mintzberg set to take over in August. Mintzberg joins amid challenges as GBTC lost $17B following its ETF conversion, while competitors gained $30B. Despite this, Grayscale maintains strong revenues from high fees and rising crypto prices. Managing $30B in assets, Grayscale played a key role in securing regulatory approval for spot Bitcoin ETFs by suing the SEC.
