BNB (BNB) Exchange

BNB started as an exchange token and became the gas coin of BNB Chain, an EVM-compatible network where blocks arrive every three seconds and fees are a few cents. Every transaction on that chain — a transfer, a swap, a contract call — is paid for in BNB, which is the main reason to hold any.

The supply shrinks over time: the issuer burns coins quarterly against a published schedule, with a stated target of halving the original two hundred million. Whether that supports the price is a matter of opinion, but the burns themselves are verifiable on chain.

BNB Chain runs a small set of validators, which is what buys the speed and the low fees, and also what makes it more centralised than Ethereum. For everyday transfers that trade-off is usually invisible; for anything where censorship resistance matters, it is the thing to weigh.

In swaps BNB behaves like the other network coins: people acquire it to cover fees on BEP-20 transfers and to interact with contracts on the chain, and sell it back when they are done with that network.

Practical points for a swap. BNB Chain uses the same address format as Ethereum, and wallets happily show one address for both — which is how transfers end up on the chain nobody was watching. The label in your wallet (BEP-20 versus ERC-20) is the part that matters, not the address itself.

There is also an older Beacon Chain format starting with bnb1, used by some exchanges for withdrawals and requiring a memo. If a service asks for a memo along with the address, sending without it means the transfer arrives at the exchange but not at your account, and recovering it takes a support ticket.

Two more things decide whether BNB belongs in your wallet. First, the chain hosts a large share of low-cost token activity, so if you interact with any of it, you need the coin regardless of what you think of it. Second, the exchange behind it uses BNB for fee discounts and launch participation, which is a separate reason people hold it and has nothing to do with the chain itself.
