Of course, burning coins can increase the price of these coins, because the circulation supply has decreased. Apart from that, the staking system is activated. Binance often does a staking system for BNB coins, so the price of BNB coins can increase without having to wait for a typical bull run. I think Binance uses a lot of methods in pumping up the price of the coin.
And of the several methods implemented by Binance, only the Launchpad and staking methods are able to run smoothly and can also help increase the price of the BNB coin even though it doesn't experience a pump in a large percentage size, it is clear that BNB holders are always kept away from losses during the market is not bearish.
