The hack on CoinEX comes as the crypto sector navigates a market lull that has most coins way off their last bull cycle peak. But more notably, it highlights the continuing risks and challenges facing the crypto industry as it trends towards mainstream adoption.

As reported earlier today, experts see the growing institutionalization of crypto via ongoing backing from the likes of BlackRock as critical to its maturity.
