I experienced this issue yesterday—funds from selling US stocks couldn't be transferred to the futures account, only between the spot account and the funding account. But it’s back to normal today. I figured it might have been due to the complex settlement process causing a delay after selling. For those who urgently need funds, I recommend being prepared. The Binance team should also remind users in time to avoid situations where urgent use of USDT gets stuck. It would be even better if instant and free transfers could be implemented. @cz_binance @binancezh @sisibinance
