Coinbase CEO Armstrong and two insiders file to sell up to $2B in stock

Coinbase CEO Brian Armstrong and two insiders, president Emilie Choi and board member Frederick Ehrsam, have filed to sell up to $2B in stock. Armstrong's plan covers about 60% of the 13.6 million shares involved. Large insider sales can signal executives see limited upside, and traders often read them as a mild negative for COIN even when they are pre-scheduled diversification moves.
