The “Tokens but No Gas” Problem on BNB Chain
BEP-20 tokens, including USDT, need BNB for every transaction. If someone sends you USDT on BNB Chain and you hold no BNB, you cannot even swap it. The fix is to bring BNB from another network: choose USDT, USDC or ETH on Ethereum or another chain as the source and BNB on BNB Chain as the destination. A few dollars of BNB is enough to unlock the rest.
How Much BNB to Keep
| Use | Suggested BNB balance |
|---|---|
| Occasional transfers | 0.002-0.005 BNB |
| Regular swaps and DeFi | 0.01-0.02 BNB |
| Approvals plus several swaps a day | 0.02+ BNB |
