The burn is already done? Why is the price keeps dropping then?
Burn has been done and prices are still going down. You should be aware that we all don't know when Binance buy back tokens to burn. So even though currently the token has been burned, it will not affect the price.
Because it could be that yesterday BNB went up high is the effect of the buyback
How long in advance does Binance announce the BNB burns? Does that happen on a regular basis or every now and then?
If it is every now and then those with that insider information definitely have an advantage over the rest of the market. Why don't they have a fixed schedule?
