Let's give you the bottom line first: for your first crypto purchase on Binance, start with about 100-500 RMB just to test the waters, and get the whole process down before putting in more. For your first three months, don't let any single coin exceed 30% of your total invested capital, and don't let your overall crypto allocation exceed 10%-20% of your liquid assets. Always keep at least 50% in cash so you can average down or add to a position. The number one reason beginners lose money isn't picking the wrong coin — it's overexposure combined with having no cash left to deploy. Start by opening the Binance Official Site, Android users should go through the Official Binance App, and iPhone users should reference our iOS installation guide.
Below, we'll walk through exactly how much to invest, how to allocate it, how to add to your position, and when (if ever) all-in makes sense.
The point of your first spot trade isn't to make money — it's to get comfortable with the process. You need to walk through these actions at least once:
100 RMB is enough to run through this entire process. Buy 0.001 BTC, 0.005 ETH, and 0.05 BNB, one at a time — roughly 30-50 RMB per coin — plus the USDT you deposit via C2C, for a total of about 100-200 RMB.
Once you've run through this once, you'll have a real feel for things: you'll know what the Binance interface looks like, where the order button is, where to check your balance, and how much you're paying in fees. That experience is worth far more than the 50 RMB you might make from picking the right coin.
Crypto is extremely volatile, and you need to assume this money could drop 50% by tomorrow and 80% within six months. Only capital you can afford to lose without it affecting your life is reasonable crypto principal.
Here's a reference formula:
| Financial Situation | Recommended Crypto Allocation of Liquid Assets |
|---|---|
| Student / just started working (no savings) | 0% (not recommended) or a 1,000 RMB test amount |
| 1-3 months of living expenses in emergency savings | No more than 5% |
| 6 months of living expenses in emergency savings | No more than 10% |
| 12 months of living expenses + stable income | No more than 20% |
| Financially independent / investing is your main activity | Up to you — 30%+ is fine |
Here's an example: you earn 10,000 RMB/month and have 60,000 RMB in savings. Take your liquid assets as 60,000 RMB minus 6 months of living expenses, which equals 0. In this case, your crypto principal should be 0, or at most a 1,000 RMB test amount. Forcing in 5,000 RMB anyway, and then losing it, will wreck your mindset.
If instead you have 300,000 RMB in savings and earn 20,000 RMB/month, your liquid assets are 300,000 minus 60,000 for living expenses, which equals 240,000. A 10% allocation would be 24,000 RMB, invested gradually.
Total principal doesn't mean buying it all at once. Even if you decide to put 10,000 RMB into crypto, you should still spread it across multiple coins and multiple purchases.
Here's a recommended allocation for a beginner's first three months:
| Coin | Allocation | Role |
|---|---|---|
| BTC | 30%-40% | "Digital gold," relatively lower volatility |
| ETH | 20%-30% | Leading smart contract platform, large ecosystem |
| BNB | 10%-15% | Exchange token, covers your trading fees |
| Stablecoins USDT/USDC | 30%-50% | Your cash reserve |
After the third month, once you're more comfortable, you can consider adding a few other major coins (SOL, ADA, etc.), keeping any single one under 10%.
Note that the stablecoin portion isn't wasted capital — it's your ammunition. When the market drops 20%, you can still buy in and lower your average cost; without cash on hand, all you can do is watch your losses grow.
Going all in is the most fatal mistake a beginner can make. There are four reasons.
First, crypto is far more volatile than traditional finance. BTC has dropped 80% in a single year multiple times in history (2018, 2022), and a 95% drop in a major altcoin is common. If you go all in and the market drops 50%, your principal is cut in half; if it drops 80%, it's nearly wiped out.
Second, having no cash reserve means losing all your agency. A market crash is often the best buying opportunity, but if you're already fully invested, all you can do is watch.
Third, there's the risk of emotional collapse. When an account is deep in unrealized losses, people make bad decisions — either panic-selling at the bottom or doubling down with leverage as a gamble. Both of these behaviors get amplified for someone who went all in.
Fourth, there's opportunity cost. If you go all in on BTC and then notice ETH is performing better, you have no cash left to add to that position — you'd have to swap positions and eat the trading fees and tax consequences. Someone holding cash can simply buy whatever they want, whenever they want.
Throughout crypto history, countless people have gone all in near the top and ended up capitulating near the bottom — ask any long-time exchange user and you'll hear this exact story.
A position shouldn't be built all at once — it should be built in stages. There are two common strategies for adding to a position.
Dollar-cost averaging:
Split your total budget into 12 equal parts and buy one part on a fixed date every month. For example, with a total budget of 12,000 RMB, you'd buy 1,000 RMB of BTC on the 1st of every month. Over a year, you keep buying regardless of whether the price is up or down, and your average cost ends up close to the year's average price. This strategy suits people with a steady paycheck — it's low-effort and doesn't require timing the market.
Staged buy-in on dips:
Split your total budget into 4-5 parts and add to your position as the price drops in stages. For example, if BTC is currently at 67,000:
This strategy works well when you believe there's meaningful room for a further pullback. If the price never reaches the second tier, the first 20% of your position still benefits from the upside.
The mistake to avoid is "chasing when it rises, panicking when it falls." Beginners most commonly go all in the moment BTC hits 70,000, then panic-sell when it drops back to 50,000. Do the opposite — buy heavily at 50,000 and take partial profits at 70,000 — and that's how you actually make money.
There are a few simple signs that tell you whether your position has gotten too big:
First, waking up in the middle of the night to check the charts. This means your position is already affecting your life, and you need to reduce it.
Second, checking the market more than 3 times a day. This means the psychological weight is too heavy — the money represents too large a share of what matters to you.
Third, panicking whenever the market drops 5%. This means your position size is more than you can handle through normal volatility. BTC swinging 5% in a single day is extremely common, and you should be able to take that in stride.
Fourth, starting to buy crypto with borrowed money. This is absolutely forbidden. Over 90% of people who buy crypto with borrowed money (credit cards, online loans, borrowing from family) end up in a bad place.
If any of these apply to you, reduce your position immediately, down to a size you can look at calmly.
Hard limit one: never let a single loss exceed 10% of your total principal.
This means once you buy a coin and it drops -10%, you should cut your losses and exit. If you don't, the loss just keeps growing — 10,000 in principal that drops 30% leaves you with 7,000, and you'd need a 43% gain just to break even, which is much harder than avoiding that initial 10% loss.
Hard limit two: never let your cumulative loss exceed 30% of your total principal.
If your account drops from 10,000 to 7,000, stop. Take a full week to calm down before doing anything else. If you keep losing down to 5,000, you'd need a 100% gain to recover — nearly impossible for a beginner.
Write these two hard limits down and stick them next to your screen. Glance at them before every order.
Say you're a beginner entering the market with 10,000 RMB to invest. Here's a reasonable initial allocation:
Week 1: transfer 200 RMB into USDT on spot, then buy 100 RMB of BTC and 100 RMB of ETH to test the process.
Month 1: transfer 500 RMB in USDT each week, dollar-cost averaging into 300 RMB of BTC, 150 RMB of ETH, and 50 RMB of BNB. That's 2,000 RMB invested over the month.
Month 2: increase your weekly contribution to 800 RMB, still split BTC 60% / ETH 30% / BNB 10%. That's 3,200 RMB invested over the month.
Month 3: keep 4,800 RMB in USDT as a cash reserve, waiting for a real pullback to add to your position. If there's no meaningful correction over these three months, just maintain your current allocation.
Following this rhythm spreads your cost basis out across 12+ weeks, avoiding the risk of buying everything at a single high point, while keeping over half your capital flexible in cash.
Q: Can I even buy crypto on Binance with 500 RMB? A: Yes. The minimum order size on Binance spot is 5 USDT (roughly 36 RMB), so 500 RMB gets you 10+ orders — more than enough for a beginner to get comfortable with the process.
Q: How much USDT should I deposit the first time? A: 100-500 RMB worth of USDT is plenty. Test the full process first, confirm you can buy, sell, and withdraw, then increase your amount.
Q: BTC keeps rising and I don't have a position — what should I do? A: Resist the urge to chase it. 80% of people who chase a rally get caught in the next pullback. Wait for a 10%-20% pullback and enter in stages. Missing a rally is far better than going all in at the top and losing half your money.
Q: Should I put everything into BTC, or diversify? A: Beginners should diversify across the three major coins — BTC, ETH, and BNB — plus stablecoins. BTC has dominated for many years, but ETH has outperformed it in certain cycles, so betting everything on a single coin isn't a good strategy.
Q: How do I reduce my position if it's gotten too big? A: Sell in batches. Sell 10%-20% each week until your position is back in a comfortable range. Dumping everything at once will hurt you through slippage and emotional decision-making.
Q: Should I hold long-term or trade short-term? A: For beginners, holding long-term is much easier to profit from. Short-term trading requires technical skill, experience, and a serious time commitment, and most ordinary people have none of the three — frequent trading tends to just compound your losses.
Q: Should I buy back in after my stop-loss gets triggered? A: No. A stop-loss is an admission that your read on the market was wrong, and you're taking the loss and exiting. Buying back in right after defeats the whole purpose of having a stop-loss system. Unless the market fundamentally changes (a genuinely new support level forms), stick to your stop-loss discipline.
Position management is the single most important — and most overlooked — skill in crypto trading. Learning technical analysis or project research doesn't come close to the value of these three rules: never go all in, keep cash in reserve, and cut your losses strictly.
