#加密安全须知
Here are some important security tips for cryptocurrency:

Wallet Security

- Choose a reliable wallet: Use well-known wallets that have undergone security audits, such as hardware wallets Ledger and Trezor, or mainstream software wallets like MetaMask. Avoid using wallets from unknown sources to prevent security vulnerabilities or malicious code.
- Backup your wallet: Always back up your wallet and securely store your recovery phrase or private key. You can use offline storage, such as writing it down on paper and keeping it in a safe place, to prevent asset loss due to device loss, damage, or software failure.
- Protect your private key and recovery phrase: The private key and recovery phrase are the keys to accessing your cryptocurrency assets. Do not disclose them to anyone, and do not enter them on untrusted websites or applications.

Exchange Security

- Choose reputable exchanges: Select well-known, reputable, long-operating, and compliant cryptocurrency exchanges, such as Binance and Huobi. You can assess the security by checking the exchange's security records and user reviews.
- Enable multi-factor authentication: Activate multi-factor authentication on your exchange account, such as Google Authenticator, SMS verification codes, or hardware tokens, to increase account security and prevent unauthorized access.
- Be cautious of phishing websites: Be vigilant in identifying counterfeit exchange websites. Ensure you are visiting the official and legitimate URL and avoid clicking on suspicious links to prevent entering phishing sites that could lead to account information leakage.

Transaction Security

- Verify transaction information: When making transactions, carefully verify the transaction amount, address, and other information to ensure accuracy. Especially when transferring funds, confirm the receiving address multiple times to prevent asset loss due to address errors.
- Avoid large concentrated transactions: Large transactions can attract market attention and may become targets for hacker attacks. Try to diversify transactions to reduce risk.
- Be aware of market risks: The cryptocurrency market is highly volatile. Before investing, fully understand the market and project risks, and develop a reasonable investment strategy without blindly following trends.

Network Security

- Use a secure network: Avoid conducting cryptocurrency-related operations on public and insecure network environments, such as public Wi-Fi. Try to use your private network or an encrypted virtual private network (VPN).

#交易对
In the cryptocurrency market, a trading pair refers to the combination of two different cryptocurrencies or the trading of a cryptocurrency against a fiat currency, used for buying and selling operations on exchanges. For example, BTC/USDT is the trading pair of Bitcoin and Tether, indicating that Bitcoin can be bought and sold using Tether. Here are some common types of trading pairs:

Cryptocurrency/Fiat Currency Trading Pairs

- Buying and selling cryptocurrencies with fiat currency as the pricing unit, commonly seen as BTC/USD (Bitcoin to USD), ETH/EUR (Ethereum to Euro), etc. These trading pairs provide a bridge between cryptocurrencies and traditional financial markets, making it easier for investors to convert fiat currency into cryptocurrencies, or vice versa.

Cryptocurrency/Cryptocurrency Trading Pairs

- Direct trading between two different cryptocurrencies, such as ETH/BTC (Ethereum to Bitcoin), LTC/ETH (Litecoin to Ethereum), etc. This type of trading pair forms a relatively independent trading system within the cryptocurrency market, allowing investors to allocate and convert assets between various cryptocurrencies based on different price trends and their own investment strategies.

Stablecoin/Cryptocurrency Trading Pairs

- A stablecoin is a type of cryptocurrency pegged to a fiat currency or other assets, with a relatively stable price, commonly including USDT, USDC, etc. Stablecoin/cryptocurrency trading pairs like BTC/USDT, ETH/USDC are often used as 'bridge currencies' in cryptocurrency trading due to the stable price of stablecoins, facilitating trades between different cryptocurrencies while also reducing the risk associated with significant price fluctuations in cryptocurrencies to some extent.

#交易流动性
Transaction liquidity refers to the ability of the market to quickly buy and sell assets at reasonable prices within a certain period of time. Here is a detailed analysis of it:

Measurement Indicators

- Bid-Ask Spread: The difference between the prices at which market makers (or market participants) are willing to buy and sell an asset. A smaller spread indicates higher liquidity, as the cost for investors to buy and sell assets is relatively low.
- Market Depth: Refers to the quantity of assets available for buying and selling at different price levels. Greater depth indicates that the market can accommodate larger transactions without causing significant price fluctuations, indicating better liquidity.
- Trading Frequency: The number of transactions that occur in the market within a certain period of time. A high trading frequency indicates an active market where assets can be quickly transacted, suggesting strong liquidity.

Importance

- Reduced Transaction Costs: In high liquidity markets, the bid-ask spread is small, and the slippage (the difference between the expected price and the actual trading price) faced by investors when executing trades is minimal, thereby reducing transaction costs.
- Improved Market Efficiency: Good liquidity allows market prices to accurately and timely reflect the true value of assets, facilitating effective resource allocation.
- Enhanced Market Stability: Ample liquidity can cushion the impact of large transactions on market prices, reducing significant price fluctuations and helping to maintain stable market operations.

Influencing Factors

- Number of Market Participants: The more participants there are, the greater the amount of capital and trading demand in the market, which typically leads to higher liquidity.
- Asset Type: For example, in the stock market, large-cap blue-chip stocks generally have better liquidity than small-cap stocks, as they attract more investor attention and trading.
- Trading Mechanism: A market maker system can increase market liquidity by providing two-way quotes; conversely, under an auction trading system, an imbalance of buy and sell orders may lead to a decrease in liquidity.
- Market Information Transparency: High transparency of information enables investors to make better decisions, attracting more participants to the market and improving liquidity.

#中心化与去中心化交易所
Centralized exchanges and decentralized exchanges are the two main types of platforms for cryptocurrency trading. Here is their introduction:

Centralized Exchange

- Operating Method: A central authority is responsible for managing transactions. Users need to deposit cryptocurrencies into the exchange's wallet, and transactions are matched by the exchange's matching engine based on user orders. Transaction records are stored in the exchange's centralized database.
- Features: User-friendly trading interface, easy to operate, suitable for beginners. Good trading depth, strong liquidity, capable of quickly completing large transactions. Offers multiple trading pairs and rich trading functions, such as margin trading, contract trading, etc. However, there is a risk of single point of failure. If the exchange's system encounters problems or is attacked, it may lead to transaction interruptions or loss of user assets. Meanwhile, user assets are held by the exchange, posing a risk of asset misappropriation by the exchange or theft due to hacking.
- Representative Platforms: Binance, Huobi, etc.

Decentralized Exchange

- Operating Method: Based on blockchain technology, using smart contracts to achieve transaction matching. Users interact directly with smart contracts through wallets for trading, and transaction records are stored on the blockchain.
- Features: Users have complete control over their assets, with private keys kept by the users themselves, ensuring high asset security. The trading process is transparent, with all transaction records verifiable on the blockchain, eliminating the need to trust centralized entities. However, the trading interface is relatively complex, requiring higher technical expertise from users. Liquidity is generally not as good as centralized exchanges, with limited trading depth, and large transactions may affect prices.
- Representative Platforms: Uniswap, PancakeSwap, etc.

#交易类型入门
Choosing the type of cryptocurrency trading requires consideration of various factors. The following is a specific analysis:

Spot Trading

- Suitable Audience: Beginners, low-risk tolerance individuals, long-term investors.
- Reason: Spot trading is simple and direct, easy to understand and operate, requiring only buying and selling cryptocurrencies at market price. It does not involve leverage, which does not amplify losses, resulting in lower capital risk. It is suitable for investors who have a long-term value judgment on cryptocurrencies and want to gain appreciation through long-term holding, such as those who are optimistic about Bitcoin's long-term development, who can buy during dips and hold for the long term.

Leverage Trading

- Suitable Audience: Individuals with certain trading experience, higher risk tolerance, seeking high returns and with a more accurate judgment of short-term market trends.
- Reason: Leverage can amplify investment returns; for example, with 10x leverage, if the price increases by 10%, the return is 100% of the principal. It is suitable for investors who can grasp short-term market fluctuations and aim for high profits in a short time. However, leverage is a double-edged sword; if the market trend is contrary to expectations, losses can also be magnified, so it is not suitable for beginners and those with low risk tolerance.

Contract Trading

- Suitable Audience: Experienced traders, familiar with technical analysis, strong risk tolerance, and capable of strict risk control.
- Reason: Contract trading allows for two-way operations, with profit opportunities in both rising and falling markets, and leverage can amplify returns. It is suitable for investors who can accurately grasp short-term market trends and profit through long and short operations. However, its trading rules are complex, and improper use of leverage can lead to significant losses, requiring constant market attention and high demands on the investor's trading experience, technical analysis ability, and risk control capability.

In summary, if you are just starting out or seeking stability, choose spot trading; if you have experience, are willing to take risks, and want to aim for high returns, consider leverage or contract trading, but first fully learn relevant knowledge, accumulate experience through simulated trading, and reasonably control risks in actual operations.

#科技巨头入场稳定币
The entry of tech giants into stablecoins is an important trend in the cryptocurrency field in recent years, with positive impacts such as promoting industry development and enhancing market competitiveness, but it also comes with risks related to regulation and financial stability, as detailed below:

- Positive Impacts:
- Promoting Innovation in Payment Systems: Stablecoins have advantages in cross-border payments in terms of low cost and fast speed, and the entry of tech giants can accelerate their application in the payment field. For example, Stripe launched a 'Stablecoin Financial Account' that allows business users to hold account balances in stablecoins across 101 countries, which is expected to reshape the global payment system, making cross-border payments more convenient and efficient.
- Enhancing Market Competitiveness: The participation of tech giants will break the dominance of Tether and Circle, promoting competition in the stablecoin market. For instance, PayPal incentivizes users to hold stablecoins by offering PYUSD yields, and in the future, there may be more measures to boost trading volume and integration, prompting stablecoin projects to continuously optimize their services and technology.
- Promoting Technology Integration and Application Expansion: Tech giants possess strong technological capabilities and rich application scenarios, enabling better integration of stablecoins with their own businesses. Platforms like Bridge allow developers to create stablecoin products within minutes through APIs, and Stripe's existing AI agent tools are also exploring stablecoin payment solutions, helping to expand the application scope of stablecoins.
- Potential Risks:
- Regulatory Compliance Risks: The regulatory policies for the stablecoin market are not yet完善, and there are significant differences in regulatory attitudes across different countries and regions. Tech giants issuing or integrating stablecoins may face regulatory uncertainties, such as challenges in choosing which stablecoin to integrate. Tether faces compliance risks, USDC is confronted with ownership change issues, and issuing proprietary stablecoins is also subject to regulatory restrictions.
- Financial Stability Risks: Without effective regulation, tech giants may become shadow banks due to their scale and influence, increasing instability factors in the financial system. Historically, money market mutual funds have experienced runs, and stablecoins may face similar risks; if a crisis of trust occurs, it could trigger systemic financial risks.

There is no unified historical data statistics for short-term high-frequency operations in cryptocurrency contracts, but we can glimpse their characteristics and risks from some cases and related market data, as follows:

- Trader high-frequency operation profit data: According to an interview with 1token, a trader with 2 years of trading experience and a capital scale of 20,000 USD, focuses on OKEX contract trading, with a daily trading volume reaching 10-20 million RMB. During good weeks, their profits can double, and during normal market conditions, they can achieve a 15% return.
- Typical case data of whale operations: On February 25, 2025, trader Liangxi achieved a hundredfold return with a 2,000 USD principal by using 50x leverage in a volatile market where ETH fluctuated over 10%. On March 2, an anonymous whale on Hyperliquid bet on long positions of BTC and ETH with 50x leverage, initially investing 6 million USDC to open a 200 million USD long position, earning 6.83 million USD in profit within 24 hours.
- Bitcoin futures market data: From the historical data of Bitcoin futures on CME, during the period from January 7, 2025, to January 13, 2025, Bitcoin prices fluctuated significantly, opening at 103,020 USD on January 7 and closing at 96,785 USD, a decline of 6.17%; on January 13, the lowest price reached 89,525 USD, and the highest price was 96,420 USD. In such market conditions, short-term high-frequency operations are suitable, but they also come with high risks. If not executed properly, one can easily incur losses due to significant price fluctuations. Similar situations occurred between March 21, 2025, and April 17, 2025, such as on April 9, when Bitcoin opened at 77,820 USD and closed at 83,600 USD, an increase of 7.52%, providing space for short-term high-frequency operations.

The above content is organized based on publicly available information and does not constitute any investment advice. At the same time, cryptocurrency contract trading is not regulated in many regions, posing significant risks, and investors should participate cautiously.

Here are some more detailed BTC investment suggestions:

Preparation Before Investment

- Knowledge Reserve: Deeply learn about blockchain technology, Bitcoin's consensus mechanism, trading principles, and other basic knowledge. Understand the core ideas outlined in the Bitcoin white paper and how it differs from traditional financial assets.
- Choosing a Trading Platform: Select a safe, reliable, compliant, user-friendly trading platform with high liquidity, such as Huobi, Binance, etc. Pay attention to the platform's security measures, such as multi-signature and cold wallet storage, to ensure asset safety.

Investment Strategy Development

- Long-term Investment: Based on Bitcoin's decentralization and limited supply characteristics, it has certain potential for value storage in the long run. You can adopt a regular investment approach, such as investing a fixed amount of money monthly or quarterly, to smooth out market volatility and reduce average costs.
- Short-term Speculation: If investors have strong risk tolerance and market analysis capabilities, they can conduct swing trading based on technical analysis and short-term market trends. However, it is important to closely monitor market dynamics and set reasonable stop-loss and take-profit levels, such as stopping losses when the price drops by 10% - 15%, and taking profits when it rises by 20% - 30%.

Risk Management

- Position Control: Do not invest all your funds in Bitcoin; manage your position based on your risk tolerance. It is generally recommended that Bitcoin investment does not exceed 20% of total assets.
- Diversified Investment: In addition to Bitcoin, also invest in other types of assets, such as stocks, bonds, gold, etc., to build a diversified investment portfolio and reduce the risks brought by the volatility of a single asset.

Post-Investment Focus Points

- Market Dynamics: Pay attention to the price trends and trading volume changes in the global cryptocurrency market, as well as the analyses and predictions from mainstream media and professional institutions, to keep abreast of market trends.
- Policies and Regulations: The policies and regulations regarding Bitcoin from various governments are constantly changing, such as tax policies and regulatory measures. These can have a significant impact on Bitcoin prices, so it is important to stay informed and adjust investment strategies in a timely manner.
- Technological Development: Pay attention to the technological upgrades and improvements of the Bitcoin network, such as the development of the Lightning Network and other layer-2 scaling solutions, as well as potential hard fork risks. These technological changes may affect Bitcoin's performance and value.

$USDC
USDC (USD Coin) is a stablecoin pegged to the US dollar, widely used in the cryptocurrency market. Here is a detailed introduction:

- Basic Information: USDC was launched in 2018 by Centre, a joint venture between Circle and Coinbase. It is a fiat-backed stablecoin, pegged 1:1 to the US dollar, meaning 1 USDC theoretically equals 1 US dollar. Its price is relatively stable, aimed at addressing the volatility of cryptocurrency prices.
- Operating Principle: When a user purchases 1 USDC with 1 US dollar, that dollar is stored in Centre's bank account, and 1 USDC is generated; conversely, when a user exchanges USDC back to US dollars, the corresponding USDC is destroyed. Additionally, when the market value of USDC deviates from 1 US dollar, arbitrageurs will buy and sell USDC to profit from the price difference, encouraging its price to return to 1 US dollar.
- Reserve Assets: Each circulating USDC is backed by 1 US dollar in cash or cash equivalents, such as short-term US Treasury bonds held by regulated US financial institutions. Circle updates the reserve information weekly and has it audited monthly by Grant Thornton LLP, providing a complete audit report to ensure the stability of the fund reserves.
- Technical Features: USDC natively exists on multiple blockchains such as Ethereum, Solana, and Avalanche, with good cross-chain compatibility, allowing transfers between different blockchain networks, facilitating users' access to various cryptocurrency application scenarios.
- Main Uses: It can serve as a bridge into the cryptocurrency market, allowing users to buy, sell, and transfer funds within the crypto ecosystem without cashing out to traditional banks; it is a commonly used token in the decentralized finance (DeFi) sector, used for providing liquidity to earn rewards or participate in lending and other financial activities; it can also be used for cross-border payments, which are faster and cheaper than traditional bank transfers, and some businesses accept USDC payments; furthermore, governments can use it to transfer relief funds and facilitate international donations.
- Market Position: It is currently the second-largest stablecoin in the market, only behind Tether (USDT), with a high market share and wide recognition, accepted by numerous cryptocurrency exchanges with substantial trading volume.
- Risks and Controversies: Although USDC claims that its assets are primarily cash or cash equivalents, the types of assets are not detailed, presenting a certain risk to transparency.
