The BNB Coin Burn refers to a mechanism in which the Binance exchange regularly "burns" a portion of its own Binance Coin (BNB) to reduce the supply and increase the value of the remaining tokens. The Binance exchange burns a percentage of the BNB supply every quarter, usually calculated based on the exchange's trading volume. The amount of coins burned is reduced each quarter until a total of 100 million BNB, equivalent to 50 percent of the original supply, have been burned. The BNB Coin Burn is an important feature that increases the scarcity of BNB and thus can potentially influence the price.
