Binance’s new CEO, Richard Teng, faces challenges in turning the world’s largest crypto exchange around after founder Changpeng Zhao pled guilty to violating U.S. anti-money laundering rules in a $4.3 billion settlement.

Analysts, investors, and former regulators claim Teng faces years of intrusive U.S. financial monitoring, a continuing SEC case, and the possibility of losing crypto sector dominance.

Four people claim Teng has a hard time changing Binance’s culture, with four people claiming it turned a blind eye to its legal obligations in the pursuit of profit.

Teng, who handled Binance’s regional markets, could face hurdles, as nearly $1 billion left the exchange in the 24 hours after Zhao’s arrested.
