Arbitrage trading is an important investment method in the cryptocurrency market. It profits by capturing price differences of assets across different trading platforms and contract types. Simply put, what is arbitrage? Arbitrage is the practice of exploiting short-term opportunities created by market information asymmetry and price discrepancies by simultaneously buying and selling the same asset to lock in profits. The most common forms of arbitrage in the current market include spot arbitrage, funding rate arbitrage, and futures contract arbitrage.
How does funding rate arbitrage generate profits?
Funding rate arbitrage is one of the most widely used arbitrage strategies in the market. In the cryptocurrency perpetual contract market, long holders are required to pay funding fees to shorts periodically, or vice versa. Traders use this fee mechanism to construct risk-free or low-risk returns.

Successful trading relies on the flexible use of multiple tools to confirm signals rather than relying on a single indicator.

The internet is undergoing its third major evolution. If the first two generations of the internet represented "one-way information flow" and "two-way interaction," then Web 3.0 technology signifies a "return of ownership" of user data. This transformation not only changes the way people interact with online services but also fundamentally redefines the underlying logic of data ownership, privacy protection, and value distribution.
The Evolution of the Third Generation of the Internet
To understand the significance of Web 3.0 technology, it is essential to review the developmental stages of the internet.
The Static Web of Web 1.0
The earliest internet (Web 1.0) was essentially an information display platform.

As the second-largest cryptocurrency asset globally, Ethereum (ETH) attracts millions of users with its smart contracts and decentralized application (dApps) ecosystem. However, every transaction requires paying a gas fee, which has become a core concern for many users. To transact efficiently on the Ethereum network, understanding and optimizing ETH gas fees is essential. As of February 2026, ETH is priced at $1.94K, with a market capitalization of $234.44B, and network activity remains high. Understanding gas fees is more important than ever.
The Underlying Logic of Ethereum Gas Fees
Ethereum gas fees are not arbitrarily priced but are based on precise measurements of network computational resources. Gas is a unit that measures the amount of computational work required to process a transaction on the network. Each transaction or smart contract execution consumes a specific amount of gas units, which are then paid for with Ether (ETH).
The calculation of gas fees involves two
