Du Yuesheng often said, 'the smaller the courage, the greater the accomplishments', which is very relevant in contract trading. In contracts, leverage is high, and volatility is significant. To earn steadily and achieve 'long-term profits', it relies not on the 'bold' who dare to go all in, but on the 'cautious' who fear risks and understand restraint — here, 'caution' does not mean not operating but knowing that the market is unpredictable, controlling greed with rules, and not letting one impulse wipe out the capital, allowing you to gradually achieve 'sustained profitability'. Many people always want to take a gamble to earn big but end up losing everything; instead, the 'cautious' steadily build their profits.
1. Don't go all in; being 'cautious' means keeping your capital for big opportunities.
The leverage of a contract is a double-edged sword. For example, with 10x leverage, if the market moves against you by 10%, you could be forcibly sold by the platform (liquidated). However, many people are greedy and go all in at once, hoping to double their investment in one go. As Du Yuesheng said, being 'cautious' here means not being greedy and going all in; generally, one should open positions of 3%-5% and keep over 70% of their money as reserves.
Just like trading Bitcoin contracts, when good news comes out, the bold directly go all in; if the news is inaccurate or if the main force suddenly dumps, they could immediately face liquidation, losing all their capital, and any subsequent good opportunities won't concern them; the 'cautious' keep a large portion of their money, even if the market moves against them by 15%, they can endure, preserving their capital for the next good opportunity — because to achieve great things, you need capital as a foundation; what the 'cautious' preserve is not just money, but the capital to do great things.
2. Stop-loss when necessary; being 'cautious' means avoiding small losses leading to big ones.
In contract trading, the worst thing to do is to 'hold onto a position': if the market goes against your expectations, the bold always think 'just wait a bit longer, and I'll break even', unwilling to stop losses, ultimately losing more and more, even leading to liquidation. But the 'cautious' don’t act this way; they set a limit beforehand, agreeing to sell if losses reach 5%-8%, and when the time comes, regardless of how reluctant they feel, they immediately close the position.
For example, in Ethereum contracts, if you short but the price keeps rising, the bold think 'it won't rise for long', even canceling their stop-loss orders. As a result, the price continues to rise, and they lose all their money, including previous profits; the 'cautious' will sell as soon as they reach the 8% stop-loss line — although they incur some losses, they still have 92% of their capital left and can earn it back the next time they find the right opportunity. Du Yuesheng's 'small courage' here means understanding 'sacrificing small losses to protect the principal' — achieving great things cannot be due to reluctance to accept a small loss, risking the entire principal; preserving capital provides the opportunity to earn more.

3. Don’t follow the crowd blindly; being 'cautious' means discerning opportunities before taking action.
Many people in contracts love to follow the crowd: when everyone in the group shouts 'the bull market is here, hurry and buy', they rush in; when they see a certain coin suddenly rise, they don't care why it rose and directly follow the trend — this is reckless operation by the 'bold'. But the 'cautious' do not act this way; they only engage in trades they understand, and do not touch those they don’t, regardless of how tempting they may seem.
For example, if a certain altcoin suddenly surges, the bold might think 'everyone is buying' and jump in too; the cautious will first ponder: is there a real positive development (like a new feature for the project), or is the main force deliberately driving up the price to fool people? If they can't articulate why it's rising, they won't buy no matter how tempting it is. This way, they can avoid many pitfalls and minimize unnecessary losses. Du Yuesheng said, 'the smaller the courage, the greater the accomplishments'. In fact, this means not gambling blindly and waiting to see the opportunity clearly before taking action — achieving great things relies on 'stability', not 'recklessness'; following the crowd for small gains can even lead to losses; only by seeing clearly can one earn steadily.
4. Survive first; being 'cautious' means enduring until the opportunity to achieve great things arises.
Contracts are not about making a gamble and leaving; to achieve 'long-term profitability', you need to endure. Changes in bull and bear markets, policy shifts, and sudden bad news (such as black swan events) will eliminate the 'bold' — they go all in, and one fluctuation could lead to liquidation, leaving them with no chance; while the 'cautious', because they follow the rules and fear risks, can endure the lows of a bear market and wait for good opportunities in a bull market.
Those who truly achieve great things in contracts often have a bit of 'caution': they don't pursue how much they can earn in one go, but first ensure they don't get liquidated. For instance, an experienced trader has consistently traded lightly and strictly followed stop-loss rules over the years, making a maximum of 20% profit per trade, but earning over 30% annually — because they have never been liquidated, their capital has always remained, allowing them to slowly build a snowball effect; whereas those who earn 10 times in one go, if they go all in next time, could lose everything, giving back all previous profits and wasting their efforts. Du Yuesheng's 'achieving great things' has never relied on one-time profits but on long-term steady efforts — 'caution' keeps you alive, and being alive allows you to wait for opportunities to achieve great things.
Conclusion:
In contracts, Du Yuesheng's principle of 'the smaller the courage, the greater the accomplishments' really means 'first control risks, then seek profits'. Here, 'cautious' means keeping positions small to preserve capital, selling to protect the principal at stop-loss points, and not following the crowd to discern opportunities. It's knowing the market is unpredictable and maintaining a bottom line. The market is never short of people willing to gamble, but those who can truly 'achieve great things' and earn long-term profits will certainly be those who are 'cautious' and understand risk control — after all, achieving great things requires capital, opportunities, and the ability to endure, all of which must be safeguarded by 'small courage'.
