This provides two major drivers of purchases of BNB that go beyond simply speculating on the token. If we do the math based on Q1 2018 profit of $200M we find that every quarter Binance is buying $40M worth of BNB . Over the course of the year that $160M worth of BNB purchases assuming Binance maintains current levels of trade. Further we can assume that most traders on Binance will recognize the savings available by paying commission with BNB and will choose to purchase and hodl enough BNB to at minimum cover commission expenses. To simplify lets assume that 100% of Binance commission is profit, so $200M commission per quarter = $800M per year. Based on this math, and considering that Binance has enough money that it doesn't need to sell BNB , we can estimate that BNB is experiencing $160M + $800M = $960M worth of recurrent annual purchases! At a current market cap of $1600M, BNB has enough forced purchases each year to cover over half of its market cap! This is exciting and leads us to believe a lot of downside protection is available to BNB hodlers.
