The cryptocurrency market in 2025 + has evolved to the 3.0 era -- Wall Street institutions are entering the market with AI trading algorithms +, and regulations in various countries are gradually tightening. The survival cycle of shitcoin projects has been shortened from 3 months to 3 weeks. In this new jungle, the era of making money by luck is completely over. Teacher Hash will use the most straightforward language to tell you the seven core abilities you must cultivate in 2025 if you want to truly gain a foothold in the currency circle
Chapter 1 Cognitive Reconstruction: First understand the rules of the game
1. Recognize the three major fundamental changes in the crypto circle in 2025
(1) Institutional slaughterhouse: BlackRock + other giants control Bitcoin pricing power; market makers use "iceberg orders" to manipulate altcoins; CME futures + gaps become a meat grinder for both bulls and bears
(2) End of regulatory arbitrage: US SEC + sues project parties in batches according to the "Howey Test"; EU MiCA regulations + require exchanges to hand over user data; stablecoin issuers need to hold 1:1 treasury bond reserves
(3) Soaring technical barriers: Zero-knowledge proof + (ZK) becomes a standard feature of public chains; modular blockchains require understanding the Celestia architecture; AI agents automatically snipe retail trading strategies
2. Establish three major meta-cognitions
(1) The market is always evolving: The "rush into shitcoins and bet on 100x" strategy in 2020 is equivalent to suicide in 2025
(2) Information difference is wealth difference: institutions have on-chain monitoring systems, and retail investors are still watching K-lines
(3) Safety is 100 times more important than income: a mnemonic leak means that ten years of accumulation is zero
Chapter 2 Survival Skill Tree: Seven essential skills in 2025
1. On-chain investigation ability
Whale tracking technique: Use Nansen to mark Smart Money addresses; be alert to "cluster behavior" (multiple whales operating synchronously); Case (1): In 2024, a fund distributed its holdings through 100 addresses
(2) Basic skills of contract auditing: Three tricks to see through the Pi Xiu disk: Check whether the Owner permission is abandoned; verify whether there is a backdoor in the Proxy contract; test whether the transaction tax can be tampered with
(3) Data cleaning technology: remove exchange wash trading data (identify fake K-lines); crack market maker order hanging patterns (iceberg order identification)
2. Technical understanding ability
(1) Four technologies that must be understood in 2025: Modular blockchain: Celestia data availability layer; ZK co-processor: application logic of Risc Zerot; intention execution: new solution to solve MEV problems; fully homomorphic encryption: breakthrough in privacy computing
(2) Technical fraud prevention guide: be alert to "AI+ blockchain" pseudo-concept projects; identify shitcoin disks that copy code (Etherscan verification)
3. Risk management system
(1) Golden rule of position control: mainstream coins (BTC/ETH) ≤50%; Layer2 leader (ARB/OP) ≤20%; high-risk speculation ≤5%
(2) Exchange Survival Manual: Enable "multi-signature + time lock" withdrawal; regularly check ProofofReserves; never use exchange financial management functions
(3) Smart contract security: hardware wallet + isolated browser; check with Revoke.cash before authorization; set daily transaction limits

1. 2025 Steady Profit Strategy
(1) Bitcoin ecosystem dividend: Participate in $tacks staking to obtain BTC income; deploy inscription protocol upgrade opportunities (2) Ethereum re-staking: EigenLayer+ node operation; choose LRT protocol with high APY
(3) RWA real yield: US Treasury tokenized products (Ondo Finance); corporate credit (Maple Finance)
2. High-yield hunting strategy
(1) Testnet Gold Rush: Interact with ZK projects (2 hours per week); capture modular blockchain airdrops (2) Memecoin Survival Rules: Only play new coins listed on the top 20 exchanges within 24 hours; "5% principal + profit rolling" strategy (3) Cross-market arbitrage: CME and currency spot price difference arbitrage: option volatility surface trading
Chapter 4 Cognitive Upgrade: Thinking beyond 99% of retail investors
1. Build an anti-fragile system
(1) Black swan contingency plan: Hold 5% cash to deal with extreme crashes: Buy Put options to hedge tail risks (2) Information filtering system: Block 99% of Twitter's calls; only follow 10 truly insightful KOLs
2. Transaction psychology combat
(1) FOMO cracking technique: Implement the "24-hour cooling-off period" rule; set automatic take-profit and stop-loss
(2) Loss aversion adjustment: allow 5% trial and error quota per month; establish an "error log" review system
Chapter 5 2025 Survival Checklist
1. Daily compulsory course: a. Check the changes of the top 50 wallets (Lookonchain) b. Scan for abnormal transactions in smart contracts
2. Weekly tasks: a. Learn 1 new technology (such as ZK circuit design). b. Interact with 2 testnets. c. Adjust position balance. 3. Monthly review: a. Change API keys and passwords. b. Offline cold wallet signature test. c. Reassess investment portfolio
Become the top predator in the new ecosystem
In the currency circle in 2025, professionalism overwhelms grassroots carnival. Remember these iron laws of survival: 1. Security is 1, and everything else is 0 --- Ten years of hard work will be in vain if you are stolen once. 2. Information difference determines wealth difference - On-chain data is the new oil 3. Time is your ally - Use compound interest to defeat volatility
Start building your crypto circle survival operating system now and become the 1% winner in the new cycle of 2025-2030.

Investment in the currency market has high returns and high risks, and risks are everywhere. Incorrect choices or operational errors may lead to unnecessary losses. In order to ensure the realization of the above income goals, it is necessary to strengthen risk awareness and take effective risk control measures. If you regard the position as a reservoir, each coin is a faucet that puts water into the pool, and the switch of the faucet must be controlled by yourself
Position Management
1. Control risks from ideas and operations.
Don't rush to buy, it is optimal to buy in installments. Follow the 334, 433 and other buying rules, enter the market in batches, and avoid doing it all at once.
You must set a take-profit and stop-loss when opening an order. When the currency price shows a clear break, technical indicators build a top, or your currency profit is greatly reduced, or even a loss has occurred, you need to take necessary protective strategies to protect your profit by taking profit in time and prevent further expansion of losses by stopping loss in time.
2. Adhere to the principle of risk diversification.
Diversify sectors and currencies. Control risks by diversifying the types of currencies held. Each fund account should avoid holding a single currency and also avoid having too many types, so that it is difficult to respond to sudden changes in the market.
Reasonably distribute long, medium and short-term positions. This is like arranging troops in battle. Funds are your soldiers. Long-term Bitcoin or Ethereum configuration must first ensure that you can definitely make money.
Other currencies should be 3-5 types. Mid-term positions should choose current hot sectors. Short-term, that is, flexible positions, are mainly speculative to capture surges. The proportion of long, medium and short-term positions should be 5:3:2 to be more reasonable.
3. Position risk control.
Control the progress of your position. Control it at 30% during the bottoming period, add it to 50% at the end of the bear market and the beginning of the bull market, and keep it above 70% when you confirm that the bull market is here. Never operate with a full position, otherwise it will not be enough to cope with sudden changes in the market.
Limit the total position. A heavy position has high returns, but also high risks. Trading should be based on changes in the market to determine the position. When the trend is good, you can take a heavy position; when the market is unstable, you should appropriately reduce your position and hold a small amount of coins for flexible operation.
Fund management and profit management
Reasonable profit management is the best way for you to earn. We must first regard the market as an ATM, not a deposit machine. As long as you don't come out, how much money you have is just a number. You must realize the money you earn instead of simply reinvesting it. Only when you put the money in your pocket is it your own money.
Instead of taking the money you earn to roll again, at least half of the profit should be placed in the fund account. This is the reserve system. Of course, you can also take out all the money you earn. Even if the funds in this operating account are lost, there are still funds to give you a new start.
Never roll the money you earn and the principal together every day. After all, no one is a god and everyone makes mistakes. Maybe one day there will be a liquidation, and you won't have a penny left, and you won't even have a chance to make a comeback.
How to follow orders to control the position
How to buy a position depends on the market. For example, when the market comes now, you need to take a heavy position, but you must also leave a certain position for risk control. This chapter focuses on short-term position control.
First, let's talk about the position control of Bitcoin and Ethereum contracts:
Stocks use 100X leverage, small position 2%-2.5%, normally controlled at 3-5%,
Contract liquidation is common. For friends who follow orders, you must set a stop loss when opening an order, and strictly prohibit single shots.
You can enter the market directly if the entry points are not far apart, because the exchange prices are somewhat different.
Reduce your position or take profit directly near the first take-profit level for each order
Let's take spot trading as an example for altcoins first:
For one currency, the sum of the three positions should not exceed 30% at most; take 3-5 currencies at most, and the sum should not exceed 70% of the total position (normal position) For one currency, the sum of the three positions should not exceed 20% at most; take 3-5 currencies at most, and the sum should not exceed 50% of the total position (conservative position) Then take leverage as an example:
2-3 layers of positions are best for 10x leverage. Exceeding 30% has already started to have risks. A larger position cannot withstand any round of sharp decline, and the fault tolerance space is too small. This is a summary of Leng Feng's years of experience. Don't take it lightly.
If you increase the leverage, you can synchronously reduce the position. If you reduce the position, you can synchronously increase the leverage, so you can ensure that it is not much different from Leng Feng. For one currency, the sum of the three positions should not exceed 30% at most; take 3-5 currencies at most, and the sum should not exceed 30% of the total position (normal position) For one currency, the sum of the three positions should not exceed 20% at most; take 3-5 currencies at most, and the sum should not exceed 20% of the total position (conservative position)
The operation of adding to your position
Adding to your position is an important part of normal trading operations
When you buy one, you must first have a concept of how much u you are going to buy. For example, I want to buy btc, a total of 1000u, buy eth, a total of 2000u, buy ordi- a total of 500u.
Secondly, there must be a rule for the progress of buying, generally a three-position system, 4.3.3 or 3.4.3 progress
If it starts to rise during the buying process, don't add to your position
If all three positions are in and it is still falling, don't add to your position anymore
I. Set a stop loss. This is necessary, not optional.
II. Add to your position but it is still falling. It means that your judgment is wrong. You can take the initiative to reduce your position first. Add to your position after it turns around.
III. Turn around and add to your position. Adding to your position is not about adding more as it falls, which can easily make your position heavier and heavier. Instead, you have to wait for it to turn around before you can
IV. There are 2 types of position adding:
One type is to reduce costs. You must come out as long as this type of position reaches above the cost price. Of course, sometimes it still falls after adding to the position. Follow the second rule.
Another type is to increase profits, which is called a flexible position. This part can be reduced according to your profit margin. Exit when the profit target is reached. You can also exit according to the resistance level, the first, second, and third resistance levels. You can reduce your position in batches or all at once.
I generally regard the first position as a basic position, and treat it as a base position. Of course, this is not set in stone either. The proportion can be increased when the market is good, and the base position can be kept smaller when the market is bad.
V. The problem of adding to a big position with a pin. In fact, it is still a problem of total position planning. If you find that you have accidentally opened a large position, you must take the initiative to reduce it. Don't take chances!
VI. Transfer position exchange issues
If we have a portfolio of 3-5 coins,
If you don't want to increase your position, you have to sell one before you can buy one, no sale no buy.
If you control your position when it falls, you must reduce the position of the weakest one.
If you don't want to increase your total position, but want to buy the strong coins you have, you can reduce the holdings of weak coins or sell the weakest coins and transfer the position to strong coins.

Observe the top and bottom to avoid risks
Look at Bitcoin before trading, and see if the recent Bitcoin market is good or bad. If Bitcoin is going to fall, everything will die. If you think the market is dangerous today and may fall, you should reduce or clear your position.
Everyone needs to know how to operate when the market may be topping. We lose money mostly in this area. When we trade and watch the market, we must first see what the trend of Bitcoin is and what trend it is in.
It may be topping or already in a downward trend. Holdings should be reduced, and the usual trading positions should also be reduced to a certain extent. As Bitcoin falls, gradually reduce long positions to ensure that your pace follows the general trend, wait for it to reach a key support, or stop falling and reverse before increasing your position again.
In a market that may be bottoming, there is no talk of bottom fishing. The bottom is slowly coming out. Short-term rebound betting should also control the position and bring a good take-profit and stop-loss.
Unless there is a K-line with a very large reversal signal.
Entering a rebound or upward trend, you can trade normally in the early stage, but be more careful as you get to the later stage, especially during critical turning points. Gradually reduce your position size and trading frequency.
Judging the time period in which the market is located is a market sense that every investor must have. If you don't even understand whether the market has risks or how big the risks are, then you lack too much basic knowledge, which cannot be explained clearly in an article or two. Friends like this, please go and study the basic knowledge of watching the market. Bitcoin's market is the most standard and simplest market among all currencies.
Relationship with Bitcoin
The Bitcoin market is obviously in an upward trend, and it has not reached a key pressure. This is the market that Teacher Jin is best at. You can be a little more casual, but you can't be crazy.
Reminder: Bitcoin is still in an upward trend today and is relatively stable. Everyone can rest assured to hold and buy.
When Bitcoin encounters a key pressure area, first analyze the key pressure in the previous analysis, and see that everyone agrees on the key pressure. After reaching this point, altcoin long positions should be cautious and should not open positions near the highest point of Bitcoin. It is safest to wait for a retracement or breakthrough for short-term trading. Mid- to long-term traders should also reduce their positions or consider leaving the market.
Reminder: Bitcoin encounters key pressure. Pay attention to the breakthrough situation. Try not to go long before the breakthrough. Focus on shorting from a high position and keep your position size small.
Bitcoin encounters key pressure and retraces. After the big pie smashes to support and stabilizes, consider short-term long positions. Lower your profit expectations and use small positions, and it is best to reduce the number of trades and coin types.
Reminder: Bitcoin is pre-stressed and retraced to support. The general trend is an upward trend. You can buy to bet on a rebound. The general trend is a downward trend. You can do a rebound with a small position.
Bitcoin falls to key support, analyze whether it may bottom out.
If the analysis is uncertain and the bottom is not reached, you cannot make high-level long orders. If you make them, you must add a stop loss behind them. It is best to reduce the number of orders and currency types.
Reminder: Bitcoin is at a key support level. Breaking through could lead to a sharp drop. Try to focus on shorting and do less long positions.
Analyze the market where the bottom may be reached and buy in batches, ensuring that the stop loss for prediction errors is within your acceptable range.
Reminder: Bitcoin has fallen to a key support level. There is a possibility of a technical rebound. You can bet on the rebound. Stable friends should wait for the bottom formation to appear.
Bitcoin is fluctuating. Pay attention to the size of the Bitcoin fluctuation range. You should not go long near the top of the Bitcoin box. Go long after breaking through, or consider long positions in the middle or at the end.
Reminder: Bitcoin is fluctuating in a box, currently in (head/middle/tail), risk from high to low.
Bitcoin has repeatedly retraced to the key support at the bottom in the short term, indicating that it is likely to be unable to hold on. Short-term suspension, mid- to long-term exit,
Multiple times are a daily-level retracement of a key support more than 4 times, but there is still no big rebound, maintaining a volatile trend, or the high point of the rebound is getting lower and lower, indicating that Bitcoin's desire to retrace is very strong.
Reminder: Bitcoin is extremely weak. Try not to open long positions. You can buy short positions in batches with small positions.
