Overview

BNB, short for Binance Coin, is the native cryptocurrency of the Binance cryptocurrency exchange. Launched in 2017, BNB initially functioned as an ERC-20 token on the Ethereum blockchain before migrating to its own dedicated blockchain network called Binance Smart Chain (BSC) in 2020. Today, BNB serves multiple purposes within the Binance ecosystem and beyond.

Primary Uses of BNB

The primary function of BNB is to reduce trading fees on the Binance exchange. Users who pay trading fees with BNB receive a 25% discount, making it economically beneficial for active traders. Beyond fee reduction, BNB serves as the native fuel for Binance Smart Chain, used to pay for transaction fees and smart contract execution.

Binance Smart Chain

When BNB moved to Binance Smart Chain in 2020, it became the backbone of a parallel blockchain network. BSC provides an alternative to Ethereum with faster transaction times and lower fees. Developers can build decentralized applications (DApps), tokens, and NFTs on BSC, using BNB for transaction costs. This expansion significantly increased BNB's utility and demand.

Investment and Supply

BNB has become one of the top cryptocurrencies by market capitalization. The token has a maximum supply of 200 million coins, providing scarcity. Binance conducts regular token burning events where a portion of trading fees are used to purchase and permanently remove BNB from circulation, theoretically increasing the value of remaining tokens.

How to Use BNB

Users can purchase BNB directly on Binance using fiat currency or other cryptocurrencies. Once acquired, BNB can be used for trading fee discounts, staking in Binance Earn programs, participating in token sales, or transferred to wallets that support Binance Smart Chain to interact with DApps.
