The Ethereum Shanghai upgrade ( EIP-4895) will be implemented in March 2023, allowing users who stake ETH to withdraw, addressing long-term Lock-up Position issues. This will drop staking risks, attract more users to participate, and promote market Liquidity, making the ETH market freer and more efficient. The price impact on ETH remains to be observed, but it helps with supply and demand balance and healthy market development.

The healthcare system is facing a series of persistent issues such as data silos, patient privacy breaches, and drug counterfeiting. Blockchain technology, due to its immutable and decentralized characteristics, is being viewed as a potential solution. But is the application of this technology in the medical field really feasible? We need to first understand what it can solve and what obstacles it faces.
How Blockchain Reconstructs the Healthcare Data Ecosystem
Secure and Trustworthy Patient Record Management
Traditional medical systems rely on centralized servers to store patient data, and once they encounter a hacker attack or ransomware intrusion, millions of patient information could be at risk. The encryption mechanism and distributed architecture of Blockchain provide another path: medical records are stored across multiple nodes, and every data change requires the consent of all participants in the network to take effect. This immutability feature significantly enhances the security level of patient data while reducing the management costs of traditional systems.

Introduction
What is the Consumer Price Index (CPI)? In simple terms, it is an economic barometer that tracks changes in the prices of everyday goods and services. However, for cryptocurrency investors, the CPI is far more than just a statistical figure — it directly influences interest rate policies, market sentiment, and ultimately determines the direction of your investment portfolio. This article will take you deep into understanding this seemingly obscure yet highly influential economic indicator.
What exactly is the CPI measuring?
The Consumer Price Index is a core tool for measuring inflation, reflecting how the prices of a representative basket of goods and services change over time. It not only concerns the erosion of purchasing power but also affects central bank decisions, corporate wage adjustments, and the formulation of investment strategies.
Specifically, the "basket" tracked by the CPI includes household daily consumption items such as food, clothing, transportation, medical care, and entertainment. Each expenditure category is weighted according to the budget share of the average consumer— for example, housing expenses account for

Quick Start
What is mining for PoW-type blockchains? Simply put, it is:
- Miners are responsible for verifying pending transactions and organizing them into new blocks, which is a key mechanism for securing the network.
- Mining also takes on the responsibility of issuing new cryptocurrencies, but is strictly bound by the rules of the protocol.
- Miners invest computing power to solve cryptographic puzzles, and the first miner to find the answer receives the block reward.
- Profit margins are affected by multiple factors: hardware costs, electricity expenses, cryptocurrency price fluctuations, and network difficulty adjustments.
How does mining sustain the operation of the blockchain?
Imagine a globally distributed ledger where every cryptocurrency transaction is recorded. Who is responsible for verifying and recording? The answer is miners.
Bitcoin ( BTC ) and other PoW blockchains rely on miners to ensure the validity of transactions. Miners use specialized computing equipment to organize transactions awaiting confirmation by solving mathematical puzzles. When a miner is the first to find a valid solution

What is token economics? Simply put, every crypto assets project operates its own economic system. Token economics is the rulebook for this system—specifying how tokens are generated, how they are distributed, and how they are used. Its essence is to find a balance between supply and demand, which directly determines the value direction of the tokens.
The practical value determines the demand.
In an ecosystem, the clearer the use of a Token, the higher the potential demand for it. Conversely, if a Token has no other application scenarios beyond trading, it is difficult to maintain long-term value. This is why designers need to give Tokens real functions—whether for payment, staking, or other uses within the ecosystem.
Governance rights and decision-making rights
Token economics also involves the distribution of power. Many projects allow Token holders to participate in the decision-making process, such as voting to choose new features, modify fee structures, or adjust resource allocation. This means that Tokens are not just assets, but more.

The contango and backwardation in futures are important relationships between contract prices and spot prices. Contango refers to when the contract price is higher than the spot price, reflecting market optimism; backwardation indicates that the contract price is lower than the spot price, reflecting market pessimism. Traders can use contango for long strategies or engage in shorting in a backwardation environment. Market drivers such as policy news and changes in sentiment can affect these two states, and successful traders need to flexibly adjust their strategies to adapt to market changes.

LP tokens are not only receipts for providing liquidity but can also be used as collateral for lending, participating in yield farming strategies, and more, helping users extract additional value. However, when using LP tokens, users should be aware of risks such as asset loss, smart contract vulnerabilities, and impermanent loss. Before entering DeFi liquidity pools, it is essential to fully understand their operation and associated risks.

What exactly is a trading symbol?
A trading symbol is the universal language of the financial markets — they are concise combinations of letters or numbers representing specific trading assets. Whether it's stocks, bonds, or Crypto, trading symbols serve as the unique identifiers for assets. Imagine if every transaction required typing out the full company name; market efficiency would plummet. That’s why "AAPL" stands for Apple, "TSLA" for Tesla, and "BTC" for Bitcoin — these simple symbols have become the common language between investors and trading platforms.
These seemingly simple characters allow investors to quickly locate target assets and execute trades without the hassle of memorizing lengthy company names. This efficient system has a long history, dating back to the 19th-century telegraph era, when stock prices were transmitted via paper tapes, making the simplicity of trading symbols crucial.

Asset under management (AUM) is an important indicator for evaluating the total amount of funds managed by investment institutions or fund managers, reflecting their market influence. Calculation methods vary; high AUM does not necessarily mean high returns, as the quality of investment strategies is more critical. AUM also affects investment fees, as management companies charge commissions based on it. Whether in traditional finance or DeFi, AUM is a universal language for assessing investment strength.

Fiat Crypto is a digital currency issued by the government that combines traditional fiat currency with cryptographic technology, bringing transformation to the financial system. It promotes the development of stablecoins, provides instant cross-border transfers and low-cost financial services, and improves market liquidity. The advancement of Central Bank Digital Currencies (CBDCs) demonstrates the potential of future financial infrastructure, allowing users to redefine the way they interact with finance.

In cryptocurrency trading, market environments are divided into two main types. Understanding how these two market states operate is the foundation for developing investment strategies. This article will delve into the characteristics of bear markets, the differences from bull markets, and profit-making methods in different market environments.
The Nature and Characteristics of Bear Markets
A bear market refers to a prolonged decline in the prices of crypto assets. During this period, investors generally feel pessimistic, selling off their digital assets in anticipation of further price drops. The entire market is shrouded in fear and uncertainty, leading to large-scale sell-offs and significant asset devaluation.
Bear markets typically exhibit the following features:
- Asset prices drop more than 20% from their highs
- Investors sell rapidly due to fear of losses
- Trading volume on exchanges noticeably shrinks
- Regulatory policies tighten, and negative news frequently appears
A classic example is the 2018 bear market, when Bitcoin dropped from $20,000

The Bank of Japan may raise interest rates, while the probability of the Federal Reserve cutting rates increases, and the market faces a dual test. Usually, a rate hike by the BOJ causes volatility in risk assets, but this time the market has already priced in the expectation, and Crypto assets are reflecting signals of capital re-pricing. The change in sentiment is both a challenge and an opportunity, and the specific impact depends on investors' response strategies.

The article discusses DOGE's market trends and technical analysis, pointing out that large holders are manipulating the market and hinting at a potential rally. Although the market performance is calm, changes in the order book indicate a possible warming-up. Two scenarios are analyzed: one is a pullback after testing the level, and the other is a genuine breakout to the upside.

In the crypto market, you've probably heard the terms "bull" and "bear." Many beginners find these concepts confusing or even mix them up. Essentially, these two ideas are: one bets on the rise, the other bets on the fall. But to truly understand their operational logic and how to apply them, you need to put in some effort.
Start with a simple example to understand
Suppose you are bullish on Bitcoin, believing it will rise from $61,000 to $75,000. The most straightforward approach is to buy directly and sell after the price increases. This is a "bull" — you are betting that the market will go up.
But what if you predict Bitcoin will fall and want to profit from the decline? How should you do it? This is when the concept of a "bear" comes into play. You can borrow a Bitcoin from the exchange and sell it immediately at $61,000. When the price drops to $59,000, you buy it back at the lower price and return it.

On December 1st, the crypto market experienced an unexpected bloodbath. Bitcoin plummeted from $93,000 to $88,500, a drop of over 4.3% within an hour, while Ethereum also declined by 5%. The entire crypto market's market cap shrank by nearly 2 trillion RMB within 24 hours, 220,000 leveraged traders were instantly liquidated, and 12.2 billion in capital vanished into thin air. This was not an isolated black swan event but a resonance of five combined shocks: "macroeconomic policy tightening + institutional capital withdrawal + regulatory uncertainty + long-term holders selling off + high leverage踩踏."
The macro cycle is an invisible killer, and the Federal Reserve is the true "Damocles' sword."
The biggest misconception in the current crypto market is viewing Bitcoin as a safe haven asset. In reality, the negative correlation between BTC and real interest rates in USD has reached 90%, rendering it a mere appendage of macro cycles.
Key data turning point in November: US job openings rose to a six-month high, inflation

In the Saudi Investment Forum in November, two tech giants gave completely different judgments on the future of work in the AI era. This dialogue seems to concern the future of careers but essentially reflects the issue of wealth distribution in technological transformation.
Two Contradictory AI Narratives
Elon Musk's conclusion is quite optimistic: in the next 10 to 20 years, AI and robots will eliminate poverty, and everyone will have sufficient material resources. Work will become optional—do it if you want, skip it if you don't. He uses the analogy of home gardening; although buying ready-made vegetables is cheaper, many people still grow their own out of interest, and the future work model will be similar.
In contrast, Jensen Huang(CEO of NVIDIA) provided empirical rebuttal: radiologists have not lost their jobs due to AI; in fact, recruitment demand has increased. The reason is that AI improves diagnostic efficiency, allowing doctors to examine more patients and handle more cases, making them busier rather than idle. This phenomenon reveals

BNB has been under continuous pressure in the past 24 hours, with the price dropping to 830.90 USDT, a 1.53% decrease from the previous day. The entire market has experienced significant volatility, with mainstream cryptocurrencies all facing pressure. Traders are watching to see if BNB can hold its current level. The breach of the important psychological threshold of $880 has caused market sentiment to become cautious, and the future trend will depend on the overall market recovery.
