What is BNB?
BNB (originally Binance Coin, now Build and Build) is the native token of BNB Smart Chain. Every transaction on BSC requires a small amount of BNB to pay gas fees — similar to how ETH is needed for Ethereum transactions.
How much BNB do you need?
For typical DeFi interactions on BSC:
- Simple token transfer: ~$0.01 in BNB
- DEX swap: ~$0.03–$0.05 in BNB
- DeFi protocol deposit: ~$0.05–$0.10 in BNB
A starting balance of $5–$10 worth of BNB is sufficient for hundreds of transactions.
How to get BNB
- Buy on Binance — the most direct route
- Buy on any CEX that lists BNB (Coinbase, Kraken, etc.)
- Bridge from Ethereum — using official BSC bridge
- Buy on a BSC DEX — if you already have USDT on BSC
BNB price volatility
BNB's price fluctuates like other cryptocurrencies. For DeFi users, this means your gas fee costs in USD terms vary. Keep a small BNB reserve for fees but don't hold large amounts unless you want BNB price exposure.
BNB in the TurboLoop ecosystem
You need BNB to pay gas fees when depositing to and withdrawing from TurboLoop. Your principal and yield are in USDT/USDC — BNB is only needed for the transaction fees themselves.
