The prospect of Ethereum's (ETH) market capitalization surpassing the most popular cryptocurrency's market capitalization is referred to as "flippening," a word that became popular in 2017. The phrase, therefore, refers to the speculative time in the future. The market capitalization (market cap) of a cryptocurrency is generally calculated by multiplying the circulating supply by the current market price (although some calculations exclude lost coins or tokens). Many Ethereum backers were wishing for the Flippening to occur around mid-2017 and early 2018. Speculators predicted that Ethereum would experience Flippening due to its great flexibility and the capacity to create smart contracts, however, the Flippening never actually happened.
