The opposite of Bitcoin domination in which the market capitalization of Ethereum exceeds that of Bitcoin.
Flippening is the term used to describe any point at which the market capitalization of Ethereum (ETH) surpasses that of Bitcoin (BTC). The concept is popular because of Bitcoin’s domination as the number one crypto asset to date, which means that it is almost always at the top of the market when compared to other cryptos. ETH founders, users and promoters believe the coin is better than bitcoin in every way and that its market capitalization will eventually reflect its superiority.
Flippening is usually used by the ETH community, and it is meant to show that ETH has the potential and capacity to surpass BTC. However, it has not happened yet.
