关于【Cryptocurrency】问题列表

In the crypto market, Bitcoin makes the headlines, but Tether (USDT) provides the liquidity. As the most widely used stablecoin in the world, USDT is the bridge between the volatile crypto world and the stability of the US Dollar.

For a trader, understanding USDT trading pairs is not just about knowing which coin to buy; it’s about understanding market sentiment, liquidity, and how to lock in profits effectively.

In this guide, we go beyond the basic list to explain the most critical USDT pairs and the strategies seasoned traders use to profit from them.

Why Trade USDT Pairs Instead of BTC Pairs?

Before we list the top pairs, you must understand why you are using them. In crypto, you can trade a coin against Bitcoin (e.g., ETH/BTC) or against Tether (e.g., ETH/USDT).

Why beginners and pros prefer USDT pairs:

1. Simplicity in Profit Calculation: When you trade ETH/USDT, you know exactly how many "dollars" you made. Trading against BTC requires you to constantly calculate the value of Bitcoin itself, which fluctuates.
2. Stability: If the entire market crashes, holding USDT protects your portfolio's dollar value. Holding a BTC pair during a crash means your "cash" position is also losing value.
3. High Liquidity: USDT pairs almost always have the highest trading volume, meaning you can enter and exit large positions instantly without "slippage" (losing money due to a lack of buyers).

The "Big Three" Pairs You Must Watch

Even if you are trading obscure meme coins, you must keep an eye on these three pairs. They dictate the direction of the entire market.

1. BTC/USDT (The Market Mover)

This is the single most important chart in crypto.

• Why it matters: Bitcoin leads the market. If BTC/USDT drops 5%, almost every other coin will follow.
• Strategy: Always check the BTC/USDT trend before opening a trade on any other coin. It is your weather report.

2. ETH/USDT (The Altcoin Leader)

Ethereum is the leader of the "Altcoins."

• Why it matters: If ETH/USDT is rising while Bitcoin is stable (sideways), it often signals the start of an "Altseason," where smaller coins explode in value.

3. SOL/USDT (The Volatility Play)

Solana has become a favorite for active traders due to its high volatility and liquidity.

• Why it matters: For traders looking for quicker, larger swings than Bitcoin can offer, SOL/USDT has become the go-to pair for day trading.

The "Stablecoin Swing" Strategy

One of the most powerful strategies involving USDT pairs is defensive trading.

In traditional stocks, if the market crashes, you sell for cash. In crypto, you swap to USDT.

• The Strategy: When the market enters a downtrend (Bear Market), successful traders sell their volatile assets (BTC, ETH) into USDT.
• The Goal: They sit in USDT (earning 0% but losing 0%) while the market drops 50%. Then, they use that USDT to buy back more Bitcoin at the bottom.

This is only possible because of the deep liquidity of USDT pairs.

Risks to Consider: The "De-Peg"

While USDT is stable, it is not risk-free. A "de-peg" happens if USDT drops below $1.00 (e.g., to $0.98). While rare and usually temporary for USDT, traders should diversify.

• Tip: Keep an eye on USDC/USDT pairs. If huge volume flows into this pair, it might mean whales are nervous about one of the stablecoins.

Conclusion

USDT pairs are the lifeblood of your trading strategy. They offer the clarity of cash with the speed of crypto. By focusing on high-liquidity pairs like BTC/USDT and knowing when to sit in stablecoins, you stop gambling and start managing your risk like a professional.

Crypto For Beginners: The Shocking Truth About Whether You Should Invest

Bitcoin hits a new all-time high. A meme coin makes a millionaire overnight. Your cousin won't stop talking about his  altcoins.  It feels like everyone is making money in cryptocurrency except you.

But then you hear the other side of the story: the crashes, the scams, the confusing jargon. You're left with one burning question, echoing in the minds of millions: Is crypto a good investment, or is it a massive bubble waiting to pop?

The truth is, the world of digital currency is both thrilling and terrifying. This guide is designed to cut through the noise. We're going back to cryptocurrency basics, breaking down what you need to know to make an informed decision. Whether you're looking to dip a toe in or just finally understand what the fuss is about, you're in the right place.

Crypto Demystified: What in the World Is Cryptocurrency?

Let's start with the absolute foundation. If you're understanding cryptocurrency, think of it as digital money.

Unlike the dollars in your bank account (which are controlled by governments and central banks), cryptocurrency is decentralized. This means it operates on a network of computers spread across the globe, using a technology called blockchain.

The Magic of Blockchain: A Digital Ledger You Can Trust

Imagine a giant, transparent spreadsheet that records every single transaction. This spreadsheet isn't stored in one location but is copied across thousands of computers worldwide. Whenever a new transaction occurs, it's added as a  block  to a chain of previous transactions.

1- Transparent: Anyone can view the transaction history.

2- Secure & Immutable: Once a block is added, it's nearly impossible to alter or delete it. This makes it incredibly secure against fraud.

3- Decentralized: No single entity, like a bank or government, controls it.

This technology is the engine under the hood of every crypto project. It’s what makes digital money without a central authority possible.

Is Bitcoin the Same as Cryptocurrency? (Spoiler: No!)

This is one of the most common misconceptions in the space. Let's clear it up right now.

Bitcoin is a type of cryptocurrency, but not all cryptocurrency is Bitcoin.

Think of it this way: Toyota is a car brand, but not all cars are Toyotas.

1- Bitcoin (BTC): Created in 2009 by the mysterious Satoshi Nakamoto, it was the first cryptocurrency. Its primary goal was to be a decentralized digital cash system, a peer-to-peer electronic cash system.  It's often seen as  digital gold —a store of value.

2- Altcoins (Alternative Coins): This is the term for every other cryptocurrency that came after Bitcoin. This includes thousands of projects like Ethereum (ETH), Solana (SOL), and Cardano (ADA). These often aim to do more than just be money; they power applications, smart contracts, and entire digital ecosystems.

So, when you're investing in crypto for beginners, you're not just buying Bitcoin. You're exploring a vast universe of digital assets, each with its own purpose and potential.

The Million-Dollar Question: Is Crypto a Good Investment?

The Bull Case: Reasons for Optimism

1- Potential for High Returns: Let's not sugarcoat it; the primary allure is the potential for significant growth. Early investors in Bitcoin or Ethereum have seen life-changing returns.

2- Decentralization and Freedom: Crypto operates outside the traditional financial system. This can be appealing for those concerned about inflation, government control, or who want more autonomy over their money.

3- Technological Innovation: Blockchain technology is powering new frontiers like Decentralized Finance  , Non-Fungible Tokens (NFTs), and Web3, which could reshape the internet as we know it.

4- Diversification: Adding a small amount of crypto to a well-balanced investment portfolio can provide diversification, as its price movements don't always correlate with traditional stocks and bonds.

The Bear Case: The Real Risks You Can't Ignore

1- Extreme Volatility: Crypto prices can swing wildly. It's not uncommon to see a 10-20% drop in a single day. You must have the stomach for this.

2- Regulatory Uncertainty: Governments around the world are still figuring out how to regulate crypto. New laws or crackdowns can significantly impact the market.

3- Security Risks: While blockchain itself is secure, the ecosystem around it isn't foolproof. Hacks on exchanges, phishing scams, and user error can lead to lost funds.

4- The  Fear of Missing Out  (FOMO) Trap: Many beginners buy at the peak of a hype cycle out of FOMO, only to panic-sell during the inevitable dip. This is the fastest way to lose money.

The Verdict: Crypto can be a good investment, but only if you approach it with caution, do your own research, and never invest more than you are willing to lose entirely.

Your First Steps: A Beginner's Blueprint to Investing in Crypto

Ready to take the plunge? Here’s a step-by-step guide to investing in crypto for beginners.

Step 1: Get Educated (You're Already Doing This!)

Before you spend a single dollar, spend time learning. Understand wallets, exchanges, and the projects you're interested in. This article is your starting point, not the finish line.

Step 2: Choose a Reputable Crypto Exchange

This is your on-ramp. You need a platform to buy your first crypto with your local currency (like USD, EUR, or GBP). Look for:

1- Strong security measures (like 2-factor authentication)

2- A user-friendly interface

3- Good customer support

4- A wide selection of coins

In the world of crypto trading, especially on Decentralized Exchanges (DEXs), there's a high-speed game happening just beneath the surface. It's a world of automated bots, strategic bidding, and transactions that seem to happen with impossible foresight. This is the world of frontrunning.

You may have heard the term, or perhaps you've noticed a trade that executed at a slightly worse price than you expected. You weren't imagining it.

As your guide, I'm going to pull back the curtain on this practice. We'll explore what a frontrunning bot is, how it operates in the wild, and most importantly, what it means for your trades.

What is Frontrunning? A Simple Analogy

Before we dive into crypto, let's start with a classic example. Imagine a stockbroker receives a massive "buy" order from a wealthy client. The broker knows this huge order will drive the stock price up. Before executing the client's order, the broker quickly buys some of the stock for their own account. Then, they execute the client's massive order, the price shoots up, and the broker immediately sells their own shares for a quick, risk-free profit.

That is frontrunning. It's the act of using privileged information about a pending transaction to make a profit.

How Does Frontrunning Work in Crypto? The Mempool

In crypto, there isn't a broker; there's something far more public: the Mempool (Memory Pool). Think of the Mempool as a public "waiting room" for all pending transactions on a blockchain like Ethereum. Before a transaction is confirmed and added to a block, it sits in this waiting room, visible to everyone.

This is where the frontrunning bot crypto comes into play. These are highly sophisticated automated programs that constantly scan the mempool for large, pending transactions.

Here's the process:

• The Scan: A frontrunning bot spots a large "buy" order for a token on a DEX in the mempool. It knows this order will increase the token's price.
• The Front-Run: The bot instantly copies the user's trade but submits it with a slightly higher "gas fee" (the transaction fee). Think of this as giving a bigger tip to the miners/validators to get your transaction processed first.
• The Squeeze: The bot's "buy" order is executed just moments before the user's original order. This pushes the price up slightly.
• The User's Trade: The user's original buy order now executes, but at the new, slightly higher price caused by the bot.
• The Back-Run: The bot, sensing the user's buy pressure, immediately sells the tokens it just bought for an instant profit.

The "Sandwich Attack": You're the Filling

This entire sequence is famously known as a "sandwich attack." The user's trade is the filling, sandwiched between the bot's initial buy and its subsequent sell. The bot makes a profit on the price difference (the "slippage"), and the user ends up with a worse execution price than they should have.

The Sobering Reality and How to Protect Yourself

"So," you might ask, "can I run one of these bots?" The honest answer: it's an incredibly competitive, technically demanding, and ethically gray area dominated by expert teams with significant capital. For 99.9% of traders, it's not a viable path.

The more important question is: how do you avoid being the victim?

• Use Low Slippage: When trading on a DEX, set your slippage tolerance as low as possible (e.g., 0.5% or 1%). This limits the profit potential for a frontrunning bot.
• Use Anti-Frontrunning Tools: Some services offer private transaction relays (like Flashbots Protect) that send your transaction directly to miners, bypassing the public mempool.
• Trade on a Centralized Exchange (CEX): This is the most straightforward solution. On a platform like BYDFi, the order book is not a public mempool. The exchange's internal matching engine provides a controlled environment, protecting you from these specific types of public frontrunning attacks.

While the wild west of DeFi can be exciting, it comes with unique risks. Understanding them is the first step to protecting your capital.

Introduction

The crypto market is moving faster than ever. With 24/7 volatility and thousands of new assets launching weekly, keeping up is a full-time job. Enter Crypto Copy Trading. This strategy allows you to automatically mirror the positions of experienced master traders. In 2026, it’s not just about convenience—it’s about survival. Whether you are a total beginner or a busy professional, copy trading levels the playing field.

What is Crypto Copy Trading?

Imagine having a pro trader sitting next to you, executing every trade for you the second they spot an opportunity. That is copy trading. When they buy Bitcoin, you buy Bitcoin. When they short a meme coin, you short it too—automatically and proportionally to your account size.

Why 2025 is the Year of Social Trading

• Institutional Tools for Everyone: Platforms like BYDFI now offer "Perpetual Contract Copy Trading," giving retail users access to complex derivatives strategies previously reserved for hedge funds.
• The Return of Volatility: With the market heating up, manual trading often leads to emotional mistakes. Copying a disciplined trader removes the emotion from the equation.
• Low Barrier to Entry: You no longer need thousands of dollars. On modern exchanges, you can start copying with as little as $10.

How to Start Copy Trading on BYDFI

1. Browse the Leaderboard: Look for traders with consistent long-term gains, not just one lucky week.
2. Check the Drawdown: A trader with 500% profit but 80% drawdown is risky. Look for stability.
3. Allocate Funds: Don't put all your eggs in one basket. Split your capital across 3-5 different "Master Traders."
4. Monitor and Adjust: If a trader's strategy changes, don't be afraid to unfollow and switch to a new one.

Let’s be real for a second. We call Bitcoin "crypto-currency," but it fails at one crucial function of currency: Fungibility.

If you receive a Bitcoin that was previously used in a hack, exchanges might freeze your account. Your money is "tainted." Furthermore, your entire financial history is visible on the blockchain for your neighbors, your boss, and the government to see.

Monero (XMR) fixes this.

Monero is what people think Bitcoin is: completely anonymous, untraceable, and uncensorable digital cash. It is the "bad boy" of the crypto world, hated by regulators but loved by cypherpunks. In this expert review, we analyze why Monero remains the undisputed King of Privacy and whether it belongs in your portfolio.

What is Monero and How Does It Work?

Monero is a Proof-of-Work cryptocurrency launched in 2014. Unlike Zcash (where privacy is optional) or Bitcoin (where privacy is non-existent), Monero is Private by Default.

This means you cannot accidentally send a transparent transaction. Every single transfer is encrypted. To achieve this, Monero uses three specific technologies:

1. Ring Signatures: When you sign a transaction, the network mixes your signature with a group of past transaction signatures. It creates a "decoy" crowd. An observer knows someone in the group moved money, but they can't tell it was you.

2. Stealth Addresses: For every transaction, a one-time unique address is created. Even if you post your wallet address on Twitter, nobody can look it up to see your balance.

3. RingCT: This hides the amount of money sent.

The Concept of Fungibility (Monero vs. Bitcoin)

This is the most important economic argument for Monero.

Fungibility means that one unit of a currency is identical to another. A $10 bill in my pocket is worth the same as a $10 bill in your pocket, even if yours was used in a drug deal yesterday.

• Bitcoin is Non-Fungible: Because of chain analysis, "clean" Bitcoins (mined fresh) trade at a premium over "dirty" Bitcoins (linked to crime).
• Monero is Fungible: Because no one can trace the history of an XMR coin, 1 XMR always equals 1 XMR. Exchanges cannot reject a specific Monero coin based on its past history because the past history is invisible. This makes Monero the closest thing we have to digital physical cash.

Mining Monero: The People’s Coin (RandomX)

Most cryptocurrencies eventually get dominated by massive corporate mining farms using expensive ASICs (specialized hardware).

Monero fought back. It uses a mining algorithm called RandomX that is designed to be ASIC-Resistant.

• What this means: You can mine Monero efficiently using a standard CPU (like the processor in your laptop or gaming PC).
• The Result: Monero has one of the most decentralized mining networks in the world. It is truly run by the people, not by corporations.

The Regulatory Risk: Why Exchanges Delist XMR

If Monero is so good, why isn't the price $10,000?  Fear of Delisting.

Governments want to track money flows to prevent tax evasion and money laundering. Because Monero makes this impossible, regulators pressure centralized exchanges (CEXs) to remove it. Major exchanges like Binance and Kraken have delisted XMR in certain regions.

• The Bear Case: If it becomes too hard to buy/sell XMR, the price drops due to lack of liquidity.
• The Bull Case: This proves Monero works. The fact that governments fear it validates its use case. As long as decentralized exchanges (DEXs) and peer-to-peer markets exist, Monero cannot be stopped.

Conclusion: Is Monero a Good Investment?

Monero is not a "hype" coin. You don't buy XMR to flip it for a quick 2x next week.

You buy Monero as insurance.
It is a bet against the surveillance state. It is a hedge against a future where CBDCs (Central Bank Digital Currencies) track every penny you spend.

If you value freedom and believe that privacy is a fundamental human right, Monero is a portfolio essential. It is the only asset that truly belongs to you and you alone.

For e-commerce merchants, chargeback fraud is a silent killer of profits. A customer buys a product, receives it, and then disputes the charge with their credit card company, leading to forced refunds and penalty fees for you. This practice, often called "friendly fraud," costs businesses billions. But there is a technology that stops it completely: cryptocurrency.

What is Chargeback Fraud and Why Does it Happen?

The traditional payment system is built to favor the consumer. If a cardholder claims a transaction was unauthorized or the product wasn't delivered, the burden of proof falls on the merchant. This system is easily abused, leaving you with lost products, lost revenue, and penalty fees.

The Blockchain Solution: Irreversible Transactions

Cryptocurrency transactions, once confirmed on the blockchain, are final and irreversible. There is no central authority like a bank that can step in and reverse a payment. When a customer sends you Bitcoin or another crypto, the payment is yours permanently. The concept of a chargeback simply does not exist.

The Benefits for Your Business:

•100% Protection from Friendly Fraud: You will never lose a sale to a fraudulent dispute again.

•Reduced Administrative Burden: No more wasting hours gathering evidence and fighting with payment processors.

•Increased Security: You take control of your revenue without needing to rely on a third party to validate your sales.

How to Get Started

The first step to gaining this protection is to implement a crypto payment gateway on your website. This service will handle the customer checkout process securely. (You can learn more in our main guide to the best crypto payment gateways).

Securing Your Revenue for the Long Term

Eliminating chargebacks means your revenue is truly yours. The final step is to manage that revenue on a secure and professional platform. Whether you want to hold your crypto, trade it for other assets, or convert it to cash, using a trusted exchange is crucial for financial management.

Why the Crypto World Is Paying Close Attention to Fantom Blockchain

The cryptocurrency space is evolving at a breakneck pace, offering developers, investors, and tech enthusiasts opportunities that were unthinkable just a decade ago. Among the rising players, Fantom blockchain has captured significant attention. But what sets Fantom apart in an already crowded market? If you’ve ever asked,  What is Fantom crypto?  or  What is FTM coin? , you’re not alone. From seasoned traders in the U.S. to curious newcomers in Europe, Fantom is turning heads thanks to its innovative approach to solving persistent blockchain challenges.

Fantom: More Than Just a Cryptocurrency

WeChat Breach Hits Binance’s New Co-CEO: A Stark Warning for Crypto Leaders in a Web2 World

In a digital era where the lines between Web2 and Web3 blur, a simple messaging app has become the latest battleground for security. Yi He, the newly appointed co-CEO of cryptocurrency giant Binance, found herself at the center of a stark reminder: even the most prominent figures in crypto are vulnerable to the inherited risks of traditional platforms.

The breach unfolded not through a complex blockchain exploit, but through the hijacking of an old, abandoned WeChat account linked to a reclaimed mobile number.  WeChat was abandoned long ago, and the phone number was seized for use. It cannot be recovered at present,  Yi He initially stated in a translated post on X, highlighting a feeling of helplessness familiar to many. While Binance later confirmed a successful recovery in collaboration with WeChat’s security team, the brief window of compromise was all attackers needed.

Seizing the Moment, Cashing In

The speed of exploitation was telling. Almost immediately after the takeover, the compromised account was used to promote a token named Mubarakah. Blockchain analysts at Lookonchain tracked the maneuver, reporting that the attackers successfully pumped the token’s price and walked away with an estimated $55,000. This incident underscores a dangerous trend: a hijacked social account is not just a personal nuisance—it’s a powerful, ready-made launchpad for financial fraud targeting a vast, trusting audience.

A Disturbingly Low Barrier to Entry

This is not an isolated event. Just days earlier in November, Tron founder Justin Sun reported a similar takeover of his WeChat. In response to Yi He’s breach, SlowMist founder Yu Xuan resurfaced a critical analysis revealing just how alarmingly simple these attacks can be.

The method, as tested, is a chilling blend of technical access and social engineering. An attacker with leaked credentials can bypass security by merely contacting two of the account’s  frequent contacts —a category that can include casual group chat members or long-forgotten connections, not just close friends. In regions like China, where mobile numbers are recycled and reissued by carriers after a few months, the risk compounds. This system opens the door to credential stuffing, SIM-swap-style abuses, and targeted manipulation of recovery processes.

Yu Xuan’s advice cuts to the core: for high-profile individuals, especially those in crypto dealing with OTC trades or sensitive wallet discussions, digital hygiene is non-negotiable. Pruning unknown contacts, regularly rotating passwords, and heeding login alerts instantly are no longer best practices but essential protocols.

Echoes from the Top: I Will Not Promote That Coin

The ripple effect of such breaches is a climate of mistrust. Binance co-founder Changpeng Zhao quickly took to X to clarify that he, too, has long abandoned his WeChat account. His preemptive warning was clear:  I would not promote any memecoin contract addresses on this account.  This statement serves as both a shield and a signal to the community—a reminder to scrutinize every message, even those appearing from the most verified of sources.

This incident is part of a worrying pattern for the ecosystem. Mere months ago, the official X account of BNB Chain was compromised, leading to phishing links and stolen user funds. While reimbursement followed, the blow to institutional credibility is harder to repair.

The Unavoidable Conclusion

The takeover of Yi He’s WeChat is more than a personal security lapse; it is a metaphor for the crypto industry’s ongoing struggle. As leaders build the decentralized future, they remain tethered to the centralized, often fragile, infrastructure of the past. The message is unequivocal: in the high-stakes world of digital assets, your weakest security link may not be your cold wallet, but an old phone number on a messaging app you forgot you had.

The guardians of Web3 must now become the most vigilant users of Web2. Their legacy, and the safety of their communities, depends on it.

You’ve probably heard the stories. A user who tried out a new decentralized exchange early on suddenly receives thousands of dollars worth of tokens for free in their wallet. It sounds like a myth, but it's a very real and powerful part of the crypto ecosystem known as an airdrop.

But what exactly is an airdrop? Is it really "free money"? And how do you find these opportunities without falling for a scam? As your guide, I'll walk you through everything you need to know about the exciting world of airdrop hunting.

What is a crypto airdrop?

In the simplest terms, a crypto airdrop is a marketing strategy where a project sends free tokens directly to the wallets of users. Think of it like a new beverage company giving out free samples at a supermarket to generate buzz and attract new customers. In the crypto world, a project gives away its own tokens to build a community and encourage the use of its platform.

Why Do Projects Do Airdrops?

This isn't just charity. Airdrops are a strategic tool with several key goals. A project might issue an airdrop to reward its earliest and most loyal users, helping to create a dedicated community from day one. It's also a powerful way to decentralize the ownership of the new token, distributing it into the hands of many different users instead of concentrating it among a few early investors. This wide distribution is crucial for the long-term health of a decentralized network.

How Do You Qualify for an Airdrop?

There is no single method, but most major airdrops in the past have rewarded users for being active and early participants in a new ecosystem. Common qualifying activities include:

• Using a New Protocol: Interacting with a new decentralized exchange (DEX), a lending platform, or a blockchain bridge before it has its own token.
• Holding a Specific NFT: Some projects airdrop tokens to everyone who owns a particular NFT from a popular collection.
• Participating in a Testnet: Helping a project test its platform before the official launch.
• Staking a Specific Coin: Staking coins like ATOM or TIA in the Cosmos ecosystem often makes you eligible for airdrops from new projects building in that network.

The core idea is to be an active, curious user of new technologies. The goal of the project is to reward the people who helped bring their network to life.

The Golden Rule: How to Avoid Airdrop Scams

This is the most important section of this guide. Because airdrops involve "free money," they are a massive target for scammers. You must be extremely cautious.

• NEVER Share Your Private Keys: No legitimate airdrop will ever ask for your private keys or your wallet's seed phrase. If they do, it is a 100% scam.
• NEVER Send Crypto to Receive Crypto: You should never have to send money to claim an airdrop. The tokens are sent to you. Any request for a "fee" or "verification payment" is a scam.
• BEWARE of Random Tokens: Scammers will sometimes airdrop a worthless, malicious token to your wallet. If you try to trade it on a shady DEX, it can trigger a malicious smart contract that drains your wallet. If you see a token you don't recognize, it's best to simply ignore it.
• TRUST Official Sources Only: Always get your information from a project's official Twitter account, Discord server, and website. Do not trust random DMs or unverified links.

The Verdict: A Real Opportunity with Real Risks

Airdrop hunting can be a rewarding way to discover new projects and be compensated for your early participation. However, it requires work, patience, and a constant state of high alert. The most successful airdrop hunters are genuine explorers of the Web3 space.

Your journey into airdrop hunting often begins with having the right foundational assets, like Ethereum (ETH) or Solana (SOL), to pay for transaction fees as you explore new protocols.
