What does “flippening” mean?
The flippening refers to a hypothetical situation in which the largest altcoin, Ethereum, surpasses Bitcoin — “digital gold” — in market capitalization. The term itself comes from the English words flip (“overturn”) and happening (“event”) and entered common usage in 2017 amid a powerful bull run* and the first large-scale growth of the cryptocurrency market.
* A bull run (bull rally) is a period of rapid price growth in digital assets.
It was precisely in 2017 that Ethereum demonstrated a sharp increase in liquidity and market capitalization, at times narrowing the gap with Bitcoin. This gave ETH supporters grounds to discuss a possible смена лидера крипторынка (change of leadership in the crypto market).
During the 2017 bull run, Ethereum’s dominance reached 28%, while Bitcoin’s share fell to 43%. These figures showed that the flippening is theoretically possible.
As of January 2026, the flippening index stands at around 20.6%. The maximum value — 85.1% — was recorded in June 2017. Since autumn 2022, the indicator has declined by more than half.
How realistic is the flippening today?
Even though Ethereum still significantly lags behind Bitcoin in market capitalization, by several fundamental indicators, it already outperforms the first cryptocurrency. A substantial role here is played by the development of the decentralized finance (DeFi) sector.
Liquidity in DeFi
Ethereum remains the key platform for DeFi protocols. According to DeFi Llama data as of January 2026, the total value locked (TVL)* on the Ethereum network exceeds $71 billion. For comparison, Bitcoin’s TVL is more than ten times smaller, placing it only in third place in this segment.
* TVL (Total Value Locked) is the total value of digital assets locked in smart contracts of decentralized finance (DeFi) protocols. The TVL metric reflects the level of liquidity, network demand, and the amount of capital used in lending, staking, liquidity pools, and other DeFi mechanisms.
User activity
In terms of daily active users, Ethereum also surpasses Bitcoin. In January 2026, this figure stood at about 765,000 users for Ethereum, versus 463,000 for Bitcoin. In addition, by the level of network activity, Ethereum consistently ranks among the top 10 blockchains.
Is a flippening possible in the coming years?
Expert opinions on this issue differ significantly. Some believe that Ethereum or a similar smart-contract platform could surpass Bitcoin in market capitalization by 2035. Others estimate the probability of a flippening at only 5%.
According to CoinMarketCap data as of January 2026, Ethereum’s market capitalization is almost five times smaller than Bitcoin’s: about $373 billion versus $1.8 trillion.
To overtake Bitcoin with BTC’s price remaining unchanged, Ethereum would need to grow by roughly 400% and exceed the $15,000 mark. So far, ETH’s all-time high stands at $4,953, set in August 2025. Forecasts of Ethereum rising to $14,000 by the end of 2025 did not materialize — nor did expectations of a flippening.
At the same time, Bitcoin’s dominance at the beginning of 2026 is about 58%, while Ethereum’s is just over 12%, despite this indicator having grown 1.5 times since 2019. If in 2017 the gap between BTC and ETH dominance was around 35%, now it exceeds 79%.
Arguments in favor of the flippening
Supporters of the flippening point to the slowdown in ETH issuance after the The Merge upgrade in 2022. Ethereum’s transition to the Proof-of-Stake consensus mechanism led to a reduction in the issuance of new coins by more than 90%. However, unlike Bitcoin, Ethereum does not have a strictly capped maximum supply, which formally makes it an inflationary asset.
An additional factor in favor of the flippening is staking*. The Bitcoin network lacks a coin-locking mechanism because it relies on mining. In Ethereum, by contrast, staking requires temporarily locking ETH, reducing the available supply on the market.
* Staking is a mechanism for participating in a blockchain based on the Proof-of-Stake consensus, in which users lock (freeze) a certain amount of cryptocurrency to validate transactions and secure the network, receiving rewards in return.
According to Dune Analytics data as of January 2026, about 28% of the total ETH supply is locked in staking — roughly $100 billion, or more than a quarter of the total supply.
Ethereum also outperforms Bitcoin due to its technological flexibility and breadth of use. It is often referred to as “digital oil,” since ETH serves as fuel for transactions across hundreds of decentralized DeFi applications.
In addition to paying fees, ETH serves as collateral in lending protocols and provides liquidity on decentralized exchanges. As Web3 continues the develop, these factors may increase the likelihood of a flippening.
Arguments against the flippening
Skeptics emphasize that Bitcoin remains a more reliable and understandable asset, especially for institutional investors. The simplicity of its concept and its status as the first digital asset contribute to its mass adoption.
In addition, the Bitcoin ecosystem is evolving through second-layer solutions* such as the Lightning Network and the Liquid Network. Specialized DeFi projects are also emerging, including Babylon Protocol, which makes it possible to implement Bitcoin restaking*.
* Second-layer solutions (Layer 2) are add-ons built on top of the leading blockchain, designed to scale the network, speed up transactions, and reduce fees without changing the base protocol. They process operations off-chain and periodically settle final data on the leading network.
* Restaking is the reuse of already staked assets to secure or operate additional networks and protocols, allowing users to earn extra income without withdrawing funds from the primary staking process.
The expansion of Bitcoin’s functionality reduces the likelihood that Ethereum will overtake it. According to several experts, a technological breakthrough is required for a flippening to occur.
The psychological factor also plays a role: Bitcoin is firmly associated with the cryptocurrency market and remains the most recognizable asset. As a rule, crypto market growth begins with BTC, and only then does capital flow into altcoins*.
* Altcoins are all cryptocurrencies other than Bitcoin, created as its technological or functional alternatives. Altcoins include both large smart-contract blockchain platforms (such as Ethereum) and specialized tokens for DeFi services, NFT projects, games, payments, and other use cases.
Analysts at Standard Chartered forecast Ethereum to reach $8,000 by the end of 2026, while expecting Bitcoin to reach $150,000. Under such a scenario, a flippening is unlikely unless the ETH supply increases significantly.
Some experts expect Ethereum to reach $20,000 in the long term; however, even then, a flippening would only be possible if Bitcoin’s price dynamics remain weak relative to current levels.
