What is Flippening?

The flippening refers to the hypothetical moment in time when the total market cap of Ethereum surpasses the total market cap of Bitcoin. The flippening has been hypothesized for many years, and may or may not come to fruition. Some crypto experts believe the flippening could occur in the mid 2020s because of Ethereum's far-reaching smart contract, decentralized finance (DeFi), and yield-farming applications.
