In the crypto world, to achieve stable profits, technical skills and connections are not essential; the key is whether you can stick to discipline. Those who survive through two bull and bear cycles all master a set of effective survival rules—today, I will share these methodologies in public, hoping to help you avoid detours.

**Identify Genuine Healthy Markets**

Market trends fall into two types: slow upward climbs with corrections not exceeding 10%, which are likely true upward trends; conversely, a sudden surge of over 20% followed by a quick drop is usually the main players cutting losses. Don’t be driven by FOMO emotions—sharp rises and falls are the most dangerous signals. Calm observation is much safer than rushing in blindly.

**Beware of Over-Marketed Projects**

The coins that are hyped the most in groups often carry the greatest risks. Phrases like "10x guaranteed" or "regret for a lifetime if missed" combined with profit screenshots may seem tempting, but truly valuable projects don’t need such aggressive promotion. Hype and value are two different things—don’t let noise influence your judgment.

**Strictly Control Single-Trade Investments**

Even if you’re very optimistic about a coin, don’t go all-in. 30% of your total assets is the safe upper limit; the remaining 70% should reserve a fallback for extreme market conditions. Those who go all-in may be wiped out by a major dip. Staying alive is always more important than chasing quick riches. For mainstream coins like $BTC, follow this ratio—no exceptions.

**Take Profits in Time**

Crypto markets change rapidly; today's unrealized gains can turn into losses tomorrow. No matter how many times your account has multiplied, first withdraw half of your profits outside the exchange, then continue to operate with the rest. This is not conservatism—it’s a rational choice based on market realities.

**Say No to Fields You Don’t Understand**

DeFi, NFT, AI concepts… new tracks keep emerging, but don’t follow the crowd just because "everyone is making money." Jumping in without understanding the underlying logic often results in you being the last to take the loss. Better to miss an opportunity than to participate incorrectly.

**Stick to Simple Methodologies**

This set of rules has helped me through two complete bull and bear cycles. They sound simple, even a bit boring, but it’s this "dumb approach" that allows people to go further in the crypto space. Being diligent and following the rules is more effective than any sophisticated technical analysis.

The crypto world is never short of opportunities; what’s lacking is the ability to be ruthless with oneself and execute plans. I hope these suggestions help more people develop rational investment habits.
