The opening price reflects the initial strength of long and short, which is significantly higher than the previous closing price and the increase in volume is a short-term bullish signal; 2. The closing price verifies the trend, breaking through the resistance level or continuously standing firm in the moving average is a sign of medium-term strength; 3. In combination of the combination analysis, the long positive line indicates a strong rise, the long negative line shows downward pressure, and the cross star indicates a possible reversal or stabilize; 4. Combining the moving average and the Bollinger band can enhance judgment. If the 5-day moving average is stable and the high opening is a long signal, the Bollinger band closes positive or oversold rebound; 5.

The total amount of Bitcoin is 21 million, which is an unchangeable rule determined by algorithm design. 1. Through the proof of work mechanism and the issuance rule of half of every 210,000 blocks, the issuance of new coins decreased exponentially, and the additional issuance was finally stopped around 2140. 2. The total amount of 21 million is derived from summing the equal-scale sequence. The initial reward is 50 bitcoins. After each halving, the sum of the sum converges to 21 million. It is solidified by the code and cannot be tampered with. 3. Since its birth in 2009, all four halving events have significantly driven prices, verified the effectiveness of the scarcity mechanism and formed a global consensus. 4. Fixed total gives Bitcoin anti-inflation and digital yellow metallicity, with its market value exceeding US$2.1 trillion in 2025, becoming the fifth largest capital in the world

The strategy of choosing altcoins in a bull market, and buying BTC in a bear market is established because it is based on the cyclical laws of market sentiment and asset attributes: 1. In the bull market, altcoins are prone to high returns due to their small market value, narrative-driven and liquidity premium; 2. In the bear market, Bitcoin has become the first choice for risk aversion due to scarcity, liquidity and institutional consensus; 3. Historical data shows that the increase in the bull market altcoins in 2017 far exceeded that of Bitcoin, and the decline in the bear market in 2018 was also greater. In 2024, funds in the volatile market will be further concentrated in BTC; 4. Risk control needs to be vigilant about manipulating traps, buying at the bottom and position management. It is recommended that the position of altcoins in a bull market shall not exceed 30%, and the position holdings of BTC in a bear market can be increased to 70%; 5. In the future, due to institutionalization, technological innovation and macroeconomic environment, the strategy needs to be dynamically adjusted to adapt to market evolution.

Novice should reasonably allocate positions to control risks. Specific strategies include: 1. Use 5%-10% of the disposable funds to participate in high-risk assets, and the holding of a single token shall not exceed 2% of the total position; 2. Mainstream assets in diversified investment account for 60%-70%, medium-sized market capitalization projects shall not exceed 20%, and emerging tokens shall be controlled within 10%; 3. Adopt the pyramid position building method, with the first investment of 30%, 5%-added 20%, and after the trend is confirmed, the stop loss of 2-3 times is supplemented; 4. Set the stop loss of mainstream assets to 8%-12%, high-risk assets to 5%-8%, and the profit exceeds 15% and mobile stop loss is enabled; 5. Rebalance every quarter, partially take profits to increase by more than 50%, reduce positions by 10%, and maintain the initial asset ratio; the core principle is to disperse allocation and strictly control single products

Batch operation is the core strategy to deal with cryptocurrency market fluctuations, which can effectively control risks and protect principal. 1. The equal-to-batch position building method divides funds into 3-5 shares, and buys one share for every 5% drop in price. The first position building is at least 10% away from the support level, which is suitable for fluctuating market conditions; 2. The pyramid-type increase invests 30% of the funds in the first transaction after the trend is confirmed, and the price decreases and increases positions when the price breaks through key resistance. The total number of times does not exceed 3 times to ensure that the cost of holding is lower than the market price; 3. The reverse pyramid-taking stop-profit technique sells 20%-30% of the position at the first target position, and the second target position is reduced by 40%-50%.
