What is BNB?

Summary: BNB is the coin of the Binance ecosystem, used to pay trading fees at a discount, to pay gas on BNB Chain, and to access token sales. It started life in 2017 as a token on Ethereum and now runs on its own network. This guide covers what BNB does, how it differs from BNB Chain, how the supply shrinks over time, and the concentration risk that comes with a coin tied to one company.

• BNB is the coin. BNB Chain is the blockchain it pays fees on. They are different things with confusingly similar names.
• Its main uses are fee discounts on Binance and gas on BNB Chain, so demand is tied closely to that one ecosystem.
• The supply shrinks on purpose through a burn mechanism, heading toward a fixed target well below the original issuance.
• The concentration is the risk: one company's fortunes drive most of what happens to the coin.

BNB is one of the largest cryptocurrencies by value and one of the least understood, partly because the name has changed and partly because the coin and the network it powers are both called BNB. Untangling that is most of the explanation.

What BNB Is

BNB was issued in 2017 to raise money for Binance, then a new exchange, and it was originally a token on Ethereum called Binance Coin. In 2019 it moved to Binance's own blockchain, and it was later rebranded simply as BNB, with the exchange presenting the letters as standing for Build and Build rather than for the company. The rename reflects an ambition to look less like an exchange voucher and more like a general-purpose network coin.

BNB vs BNB Chain

BNB Chain is a blockchain that runs the same kind of smart contracts as Ethereum, which means applications and wallets written for Ethereum work on it with minimal changes. Its selling point is low fees and fast blocks, and it carries a large volume of everyday transactions as a result. BNB is the coin you spend to use it. If someone tells you they are sending you BNB, ask which network, because the same coin exists on more than one network and sending to the wrong one is the standard way to lose it.

What BNB Is Used For

Four things, in rough order of how much they drive demand:

• Discounted trading fees for anyone paying them in BNB on the exchange.
• Gas on BNB Chain, needed for every transaction and contract interaction there. Gas fees on this network are usually a fraction of Ethereum's.
• Access to new token sales and promotions that require holding or committing BNB.
• Payments, since a decent number of merchants and services accept it directly.

Notice what these have in common. Almost all of the utility runs through one company's products or one company's chain, which is a genuine source of demand and also the whole risk in one sentence.

How the BNB Burn Works

BNB is deflationary by design. Coins are permanently destroyed on a schedule tied to network activity, with the stated aim of reducing the total supply to roughly half of what was originally issued. The reasoning offered is that a shrinking supply supports the value of what remains, which is the same argument any company makes for a share buyback, and it deserves the same scepticism: burning tokens does not create demand, it only reduces the count. Whether it matters depends on whether people want the coin for something in the first place.

The Concentration Question

This is the part worth thinking about hardest. BNB's usefulness depends on Binance continuing to operate at scale and on BNB Chain continuing to attract activity, and the exchange has had serious regulatory encounters, including a large settlement with US authorities in 2023 that saw its founder step down as chief executive. It is a reminder that the platform you hold a coin on carries its own risk. The network itself is validated by a comparatively small set of participants, which makes it fast and cheap and also less decentralized than the alternatives it competes with.

None of that is a prediction about the coin. It is the difference between a network coin whose value rests on thousands of independent participants and one whose value rests substantially on a single firm's continued good standing. Both can work. They are not the same kind of bet.

Where You Can Spend BNB

Better than most alternative coins, in fairness. Low fees on BNB Chain make small payments practical, plenty of payment processors support it, and gift cards and digital services are among the easiest things to buy with it. If you have BNB sitting there because you once needed it for fee discounts, spending it is usually simpler than converting it first.

What to Weigh Before Holding BNB

Ask what you want it for. As working capital for trading fees or BNB Chain transactions, it does a clear job and the fee discount is real money. As a long-term holding, you are taking a view on one company and one chain rather than on crypto generally, and that concentration should be a conscious choice rather than a side effect of where you happened to open an account. None of this is investment advice.

And if the balance is just sitting idle, buying a gift card with BNB costs very little on this network.
