The thing is that we will have a BNB token burn event within 2 weeks, in which they will burn a lot of tokens.
Last quarter Binance was actively working for 1 and half months, and they managed to burn $1.5m worth of tokens, how many do you think they will burn now when they $3 bln average daily volume?
I'm guessing around $15-20m, but we shall see.

But i don't think they will buy it from the market.
They would probably have too many in their hands right now. So i don't expect a pump because of burning.
