Proprietary trading firms, which bet their own capital in markets from stocks to futures, are wading into bitcoin, ethereum and other cryptoassets better known as a playground for small speculators and a haven for money-laundering.
DRW of Chicago, one of the world’s largest proprietary trading companies, has led the charge. About a dozen of its more than 800 employees buy and sell bitcoin at a subsidiary named Cumberland Mining, which was established in 2014.
