To avoid being a "sucker", you must know the basics of cryptocurrency trading.

The profit and loss law in the crypto world: There is a saying in cryptocurrency trading that "nine losses and one gain", implying that most people lose money in the crypto world while a few profit. In order to avoid losses, investors need to understand the principles of making profits.

Fund Management: Successful cryptocurrency investments require maintaining sufficient liquidity. Even in the long-term bull market of the US stock market, investment guru Warren Buffett never uses all funds for investment. This indicates that investors have no reason to fully invest all funds, let alone use leverage.

Position management: Investors should implement strict position management. Coins that do not adhere to the principle of "buying at low prices and selling at high prices" should not be established as core positions. For any currency, if it rises by 200% within three months, avoid chasing after it; after a 40% increase, do not pursue short-term profits; if it doubles, the invested capital should be withdrawn from the market first.

Investors should abandon the practice of buying solely based on favorable information, as ordinary suckers are often the last to receive such information. Instead, they should focus on reversible unfavorable information that may cause the currency to fall, and gradually buy in batches when the currency falls out of value.

Trading rules: During trading, investors need to adjust their rules according to the market conditions. Risks often increase as the currency price rises, so when the currency price rises, it is advisable to gradually sell to protect profits. On the other hand, opportunities often arise as the currency price drops, so when the currency price drops by a certain extent, it may be considered to buy in order to lower the average cost.

In summary, cryptocurrency investment requires cautious financial management, strict position control, rational analysis of news, and flexible trading strategies. Through these methods, investors can seek profit opportunities in a risk-controlled manner.
