Differences between Margin Trading and Contract Trading
Margin trading and contract trading are two common trading methods in the cryptocurrency market. Although both involve fund amplification, there are significant differences in mechanisms, risks, and application scenarios. Here are the core differences:
I. Essence and Product Types
1. Margin Trading
- Essence: Borrowing funds in the spot market to amplify trading positions (e.g., borrowing USDT to buy coins, or borrowing coins to sell).
- Underlying asset: Actual cryptocurrency held in trading (e.g., BTC, ETH), part of the spot market.
- Direction: Usually supports both long and short positions (some platforms only support one-way leverage).

Overview of Web3 Technologies and Applications
Overview of Web3 Technologies and Applications
Web3 (or Web3.0) is a new paradigm in the evolution of the internet, aiming to build a decentralized, user-controlled ecosystem based on blockchain technology. It is seen as a revolution against the current Web2.0 (dominated by centralized platforms like social media and cloud computing), aiming to address issues of data monopoly, privacy breaches, and excessive platform power.
Core Technologies of Web3
Blockchain
As the underlying technology of Web3, blockchain ensures data transparency and immutability through distributed ledgers, without relying on centralized institutions.

Cryptocurrency Trading Indicator Analysis Methods (7)
In cryptocurrency trading, **EMA (Exponential Moving Average), MACD (Moving Average Convergence Divergence), and RSI (Relative Strength Index)** are very classic and commonly used technical analysis tools. They focus on different aspects, and using them in combination can provide a more comprehensive market perspective. Here are detailed analysis methods:
## Core Concept Overview
1. EMA:
*What is it: ** A weighted average of prices (recent prices have a higher weight), more sensitive than a simple moving average, can reflect recent price changes more quickly.
*Function: ** Identify trend direction, dynamic support/resistance levels, determine bullish/bearish arrangements.

Okay, I understand your request. In cryptocurrency trading, technical indicators are important tools for analyzing price trends, identifying potential opportunities, and managing risk. **EMA (Exponential Moving Average), MACD (Moving Average Convergence Divergence), and RSI (Relative Strength Index)** are three of the most commonly used and complementary core indicators. Below, I will detail how to use them to analyze the cryptocurrency market:
Core idea: No single indicator is a "holy grail"; it is crucial to combine their use and understand their strengths, weaknesses, and applicable scenarios.

- Core Logic: EMA is more sensitive to recent prices, suitable for capturing short-term trends.
- Common parameters: 7 EMA (short-term), 25 EMA (medium-term), 50/200 EMA (long-term trend filtering).
- Long Signal:
- Bullish Alignment: Short-term EMA > Medium-term EMA > Long-term EMA (such as 7 > 25 > 50).
- EMA Cross: Short-term EMA crosses above medium-term EMA (such as 7 crossing 25), forming a 'Golden Cross'.

Cryptocurrency Market Dynamics and Policy Analysis (2025.05.09)
The following is a summary of important news developments in the cryptocurrency sector since May 2025, covering various aspects such as regulatory policies, market fluctuations, security incidents, and industry innovations:
I. Regulatory and Policy Dynamics
1. Controversy over the US MEME Act
US Senator Chris Murphy introduced the MEME Act, proposing to ban the president and members of Congress from issuing meme coins, directly targeting the personal cryptocurrency '$Trump' launched by Trump. This coin's market value once soared to $5.5 billion but has been criticized as 'the biggest corruption scandal in White House history.' House Democrats resisted the originally scheduled cryptocurrency regulatory hearing due to the Trump family's deep involvement in the crypto industry, resulting in the meeting being changed to a roundtable discussion.

The Window
When the morning dew has not yet dissipated, I often see it standing in the morning light. The sycamore tree outside the sixth-floor bay window casts slanted shadows into my white porcelain cup, causing the tea to ripple like broken gold.
In the depth of spring, this tree resembles a pipa girl dressed in green gauze. The moment the tender buds bloom is always on some unintentional early morning, as if someone has ground emeralds in the night, carefully adorning every branch. When the new leaves are half-curled, there are often a few sparrows building nests in the gaps of the leaves, their chirping mingling with the sound of an old lady downstairs beating her bedding, creating a ground full of mottled light and shadow.
I love the twilight after the sudden summer rain the most. The dusk is like light ink spreading on rice paper, dyeing the whole tree in varying shades of blue. Water droplets fall from the tips of the leaves, landing on the rusty air conditioning unit, where the sound hides a tipsy evening breeze. The Chopin nocturne drifting from the piano store across the street always weaves a transparent net with the sound of cicadas at this time.

Cryptocurrency Storage and Withdrawal Guide
Cryptocurrency purchased from an exchange does not 'go' to a physical location, but is recorded at an address on the blockchain network. Here is a detailed explanation:
### 1. Exchange custodial wallet (default storage location)
When you purchase cryptocurrency from an exchange (like Binance, Coinbase, etc.), the assets are **by default stored in the wallet address controlled by the exchange**. At this point:
- You do not directly control the private key: The exchange manages user assets centrally like a bank, and what you see is the digital balance in the exchange account.
- Exchange ownership management: Assets are actually stored in the exchange's 'hot wallet' (online) or 'cold wallet' (offline), managed collectively by the exchange.

There is Spring Thunder in the Depths of the Annual Rings
Walking through an ancient forest in twilight, the cross-section of the mossy tree stumps glimmers with amber sheen. My fingers brush over the uneven concentric circles, suddenly touching a certain flawed gap—this is the scar struck by lightning thirty years ago, now gently wrapped by the newly formed annual rings, solidifying into a badge of time.
The wild cherry blossoms in the mountains always bloom the fiercest on the cliffs. They root themselves in the rock crevices, much like a writer's ink seeping into the folds of rice paper. When the spring wind tries to push down the tilted branches, the twisted roots delve deeper into the rubble. At the steepest cliffs, one often sees vines embracing the broken brick walls, the dewdrops in the morning mist are evidence of their tears from last night, while the noon sunlight is refining the tear drops into diamonds.
