The U.S. Securities and Exchange Commission, aka SEC, decided to bust the ass of the world's wealthiest crypto bro, aka Changpeng "CZ" Zhao. They agreed to go from BNB's side to ask if the token was a security at the time of the ICO and if it was an ICO.
The crypto market responded immediately and Binance said they were ready and continuing to cooperate with regulators but considered it inappropriate to leak the negotiation process generally; there is Binance, and there is Binance US, and there is no need to confuse the warm with the soft.
Recall that Gary "Mr SEC" Gensler has previously stated that crypto exchanges trade against their customers and that all crypto ICOs are securities and should walk under his regulatory office. As usual, we wait!
