BNB is the platform token issued by Binance. For beginners, the three most practical functions are: deducting 25% of transaction fees, participating in Launchpad new coin subscriptions, and serving as the pricing basis for a large number of trading pairs. Beginners are recommended to hold 0.1-0.5 BNB (about 50-250 USD, estimated at 500 USD/coin) as a fee pool when starting, and then allocate other funds to mainstream coins such as BTC and ETH. You can directly buy BNB with USDT on the Binance Official Website or the Binance Official APP. iOS users who haven't installed the app should first check the iOS Installation Tutorial.
I. What is BNB
BNB (Binance Coin) is the native platform token issued by Binance Exchange in 2017. The total supply is gradually reduced through a quarterly burn mechanism, from the initial 200 million to a target of 100 million. It now exists on both BNB Chain (formerly Binance Smart Chain) and Binance Beacon Chain, and is the Gas fee token for the BNB Chain ecosystem.
For ordinary users, there is no need to understand the underlying technology of BNB. You just need to know that it is a digital asset in your Binance account, just like BTC and ETH, which can be bought, sold, transferred, and managed. At the same time, it has some additional uses similar to "membership points".
II. Five Core Purposes of BNB
Purpose 1: 25% Fee Deduction
This is the most direct value of BNB for beginners. After turning on the switch in "Account Center → Fees → BNB Deduction", all spot transaction fees will be deducted from the BNB balance first, and you will enjoy a 25% discount.
Example: If you place a buy order of 1000 USDT at the default rate of 0.1%, the fee is 1 USDT. After turning on the BNB deduction, the actual payment is about 0.75 USDT worth of BNB. Long-term trading can save a lot.
Purpose 2: Launchpad New Coin Subscription
Binance Launchpad is a platform for the first issuance of new projects. Historically, some projects have seen increases of several times to dozens of times after their initial launch. Participating in subscriptions requires locking BNB first, and new coin quotas are allocated based on the holding amount and days. Even if beginners can only get dozens of dollars worth of new coins each time, they can occasionally get considerable returns.
Purpose 3: Base Pricing for Trading Pairs
Binance has a large number of XXX/BNB trading pairs, and some small coins even only have BNB pricing and no USDT pricing. If you want to buy these coins, you must hold BNB first.
Purpose 4: On-chain Gas for BNB Chain
When withdrawing coins from Binance to a wallet on the BEP20 network (BNB Chain), or using DApps like PancakeSwap on-chain, BNB is required as the Gas fee. The Gas fee is usually between a few cents and 1 USD per transaction, much lower than the Ethereum mainnet.
Purpose 5: VIP Level Acceleration
Binance VIP levels are comprehensively assessed based on the spot + contract trading volume in the past 30 days and the BNB holding amount. Meeting certain thresholds for BNB balance (e.g., 25 BNB, 100 BNB) can help upgrade to VIP faster and enjoy lower fee rates.
III. Recommended BNB Holding Reference Table
| User Type | Recommended BNB Holding | Main Purpose | Amount (Estimated at 500 USD/BNB) |
|---|---|---|---|
| Pure Newbie Testing | 0.05-0.1 BNB | Fee deduction | 25-50 USD |
| Monthly Trades < 5 times | 0.1-0.3 BNB | Deduction + small amount of Gas | 50-150 USD |
| Monthly Trades 10-30 times | 0.3-1 BNB | Deduction + Launchpad | 150-500 USD |
| Monthly Trades > 30 times | 1-5 BNB | Deduction + Subscription + VIP | 500-2500 USD |
| Heavy On-chain DApp User | 3-10 BNB | Gas + DeFi collateral | 1500-5000 USD |
Beginners only need to maintain a fee pool of 0.1-0.5 BNB, and the BNB consumption generated by transactions can be replenished with the equivalent amount of fiat currency. There is no need to chase highs to buy.
IV. Risks and Precautions of BNB
Price Volatility: BNB has experienced pullbacks of 30%-50% in history. Beginners are not recommended to hold heavy positions. For small holdings as a fee pool, the impact of volatility is limited; but if taken as a main investment target, the same risk exposure as BTC and ETH needs to be considered.
Exchange Concentration Risk: The value of BNB is deeply tied to the Binance platform itself. Negative platform events (such as regulation, hackers, compliance) may directly affect the coin price. This is a special risk that other coins do not have.
Burn is Not Infinite: The deflation logic of BNB comes from quarterly burns, but the burn rhythm is disclosed by Binance, and users cannot verify it in real-time. Caution is needed when taking deflation expectations as the main investment logic.
Fee Deduction Needs to be Actively Enabled: By default, BNB deduction is turned off. Beginners often forget to turn it on, losing the 25% discount for nothing. The first thing you should do after registration is to turn on this switch.
Launchpad Does Not Equal Guaranteed Profit: Many Launchpad projects have broken below their issuance price after going online. Beginners should not treat Launchpad as a sure-win bet.
V. FAQ - Frequently Asked Questions
Q: How to turn on BNB fee deduction?
A: After logging in to Binance, go to "User Center → Fees → BNB Fee Discount" and turn on the switch. Once the switch is turned on, all spot transactions will default to using BNB for fee deduction. When the balance is insufficient, it will automatically switch back to the original currency for fee deduction, without missing any orders.
Q: Can I trade without BNB?
A: Yes. The default fee will be deducted from the coin you buy/sell (e.g., if you buy BTC, the fee is deducted from the obtained BTC). You can trade normally without BNB, just without enjoying the 25% discount.
Q: How much BNB should I buy at once?
A: It is recommended to estimate by Monthly Transaction Fee × 12. Suppose your monthly transaction fee is about 2 USD, which is 24 USD a year, equivalent to about 0.05 BNB, enough for a year. Beginners buying 0.1-0.2 BNB is completely sufficient.
Q: Can BNB spot be invested through Auto-Invest?
A: Yes. The Binance "Auto-Invest" function supports BNB periodic investment, with a minimum of 5 USDT per period. However, since BNB itself is a platform token, the volatility and correlation of investing in BNB compared to investing in BTC need to be considered separately.
Q: Compared to BTC and ETH, which one should a beginner choose?
A: From the perspective of "testing and learning", all three are acceptable. BTC is the market benchmark, ETH is the ecosystem leader, and BNB is the platform token. If you only buy one, BTC is recommended; if configuring a portfolio, you can start with 60% BTC + 30% ETH + 10% BNB, and then adjust according to your usage habits.
