The longer I stay in the crypto world, the more I feel that what truly allows you to make steady profits is not the myth of getting rich overnight, but rather the clarity to see the essence and the self-control to manage your actions.

Many people repeatedly ask me which coin to choose and how to make quick money, but after watching Bitcoin and Ethereum for so many years, what has truly helped me achieve steady growth are these 10 principles summarized from practice—no mysticism, no chasing news, all centered around "data + discipline."

1. Don't just focus on K-lines; Bitcoin's rhythm is hidden within the cycles.
I never speculate whether BTC will rise or fall tomorrow. What truly matters is its four-year "halving clock." Each halving reduces the supply of new coins, and the price will eventually reflect that. For example, after the halving in 2024, BTC rose from 16,000 to 32,000. My strategy is simple: accumulate in batches 1-2 years before the halving, and after the halving, focus on whether institutions continue to buy—like BlackRock's BTC holdings, as long as they are still increasing, I will hold on.

2. Forget the rumors and only focus on the real investments from institutions.
I have seen too many people impulsively go all in because of the phrase "immediately push to 100,000 U." But I only trust on-chain data: the changes in institutional holdings on Coinbase and Grayscale's holding trends are the true reflections of the attitudes of large funds. Since 2025, the amount of BTC purchased by institutions has increased by 30% compared to last year, and this signal is more reliable than any "insider information" in group chats.

3. Evaluate the value of Ethereum not by its price but by its ecosystem.
The value of ETH does not lie in its name "Ethereum," but in how many people are actually using it. I mainly look at two metrics: the amount staked (over 30 million coins indicates a strong long-term belief), and the daily active users on Layer 2 (like Arbitrum and Optimism exceeding one million, indicating that the ecosystem is truly operating). If these two metrics are rising, the fundamentals of ETH are solid; if the data turns around, even if the price goes wild, I will remain cautious.

4. Do not chase the price before the upgrade, look at the data after the upgrade.
Before each major upgrade of ETH, the market always tends to speculate in advance. However, I have found that after the actual implementation, there is often a phenomenon of expectation fulfillment and price correction. For example, it rose by 15% before the Shanghai upgrade in 2023, but fell by 8% after the upgrade. Therefore, my strategy is: never chase the high before the upgrade, and after the upgrade, observe the actual data—such as staking unlock situations and whether Layer2 trading volume is healthy—before deciding whether to increase positions.

5. Never go ALL IN, no matter how certain you are.
Even if I am very optimistic about BTC and ETH, I would never put all my funds into them. If I have a capital of 10,000 U, I would allocate 2,000 U each to BTC and ETH, leaving 6,000 U on hand. This way, even if they fall 10% in the short term, my total account would only retract by 4%, and my mindset would remain completely unaffected.

6. Control the position of a single coin, refuse "one coin collapse"
I have seen people put 80% of their funds into BTC, and even a slight drop can be very damaging. My principle is: no single coin should exceed 30% of the total position. This way, even if one experiences a significant correction, I still have other assets or stablecoins as a buffer, keeping my overall account stable.

7. If the floating profit exceeds 15%, sell half first to secure profits.
This is the key action for me to control "paper wealth". For example, if I buy BTC at 2000U and it rises to 2300U (a floating profit of 15%), I will sell half, recovering 1150U, while the remaining 1000U position continues to float. This way, regardless of future rises or falls, I have locked in profits and won't experience the roller coaster like many others.

8. Don't rush to make up for continuous declines, first observe the support before making a decision.
BTC and ETH occasionally experience consecutive pullbacks for 3-5 days, like the one in October 2025 when it dropped from 50,000 to 47,000. During this time, I don't blindly add to my positions, but instead, I first look at the key support levels: if it hasn't broken, I'll hold; if it effectively breaks, I'd rather reduce my position by 20% than stubbornly resist the trend.

9. Focus less on K-lines and pay more attention to on-chain data.
I only look at data for 5 minutes a day: for BTC, I check institutional holdings and the progress of the halving cycle; for ETH, I look at the total amount staked and Layer2 activity. These can be found on Glassnode and CoinGecko. If the data is healthy, I feel secure holding; if the data weakens, I become more cautious. I save the time for living and working.

10. I don't envy the wealth of altcoins; I only earn the money that I understand.
I often hear about people making several times their investment by trading small coins, but I've also seen many more people end up with nothing because of it. I see BTC and ETH as the "ballast stones of the crypto world"—though slow, they are stable enough. The BTC I bought in 2021, despite experiencing a halving in between, still tripled by 2025. I don't seek to get rich overnight; what I want is sustainable and controllable asset growth.
