Flappening is a colloquial term coined
by Charlie Lee in early 2018 to describe the moment when Litecoin (LTC) surpassed Bitcoin Cash (BCH) in terms of market capitalization
. It is a humorous play on words on the term Flippening, which is defined as the moment Ethereum
(ETH) will potentially overtake Bitcoin
(BTC) in terms of market cap. The market capitalization of a cryptocurrency
is defined loosely by its circulating supply multiplied by its current market price (although some measures don’t take into account coins or tokens that were lost).
Unlike Flippening that has not occurred as of April 2019, the Flappening actually happened as the market cap of Litecoin surpassed the one of Bitcoin Cash on the 14th of December 2018. Since this date, the use of the term has been expanded to include the overtaking of other important altcoins. The Flappening progress can be tracked at the Flappening Watch.
