$REEF on coinmarket the price of REEF IS 0.00821$. But on BNB, the spot is not listed, only Future is listed. And when the price is pushed up to a high level to carry out the following plot:

Push the price high to attract shorts and meat. The higher it is, the more shorts enter the big volume, then BNB will push the funding price up, in addition to shortening the funding fee calculation time.

BNB calculates all this, playing on the greed of the players. The nature of this Future is that the floor controls everything.
