Here are some down-to-earth insights:

1. Can you make big money relying on technology? No! It relies on market conditions. Only in a big market, if you set clear goals, maintain the right mindset, and execute the rules thoroughly, can you seize the opportunity.

2. When a big market comes, mindset is key. When the opportunity arises, as long as you avoid greed, making more or less money is just a matter of time; in a small market, even the best skills can lead to futile efforts.

3. Small-scale market? Don't engage in tricky operations. It's hardest to profit during a consolidation phase, with low tolerance for error, high transaction costs, and you can lose money in an instant. Being able to hold on is true skill.

4. The three laws of trading: win rate, profit-loss ratio, frequency; choose at most two. Want to make quick money? No way. Steady and solid, protecting your own positions is the hard truth.

5. Leverage? Don't touch it unless you have 100% confidence. Leverage is not meant to increase difficulty; it's to amplify returns, but risk also multiplies, so don't joke with your capital.

One last point: the crypto space is deep, with too many sharks, so don’t be greedy for small benefits! Many projects are outright scams, so don’t be fooled by grand promises; protecting your capital is the real victory. When opportunities arise, go in heavily, hold your positions, and stick to your logic, but above all, don't panic, don't rush, don't be greedy. Take it slow, and you can go further.
