The result of burning coins is that they will reduce the amount of coins from the supply. As a result, the supply of that coin will decrease and the price of the coin will increase. We all know that 50% of the bnb coins were burned. And as a result, the price of bnb coins is much higher now.
The main reason of Burning is reduce coin from total supply and we always believe that Low supply means following token price will more increase but it is not effective for all coin. Have Many project with Billion Token but their price is high so it is depend project's use case, team their concept etc. So low supply means more price it is not correct.
