The act of burning in the context of the cryptocurrency domain refers to the deliberate and permanent removal of a given cryptocurrency from circulation. The burned crypto coins can no longer be sold, bought, stacked, or traded. The process of burning a cryptocurrency is permanent and irreversible. 

Coin developers typically opt to burn coins in bulks as a means of taking them out of circulation. The act of burning coins is often used as a means of managing inflation in order to regulate the number of coins in circulation and maintain a stable cryptocurrency. The Binance Coin (BNB) is an example of a cryptocurrency that burns its coins on a quarterly basis. Stellar (XLM) and Bitcoin Cash (BCH) however, opt for a one-time burn of their coins.
