Starting with the most basic question: What is blockchain?
Imagine a shared notebook that everyone can see, but no one can erase. Every transaction is written down. Forever. That's it.
No banks. No middlemen. Just math and computers saying 'yeah, this happened'.
Once you get this, the rest is just details. Take small steps. You've got this.

Let's start with the key term: private key = your digital signature. No banks, no ID cards—just you and that string of letters controlling your coins. Lose it? Your money is gone. It’s as simple as that.
Step one: Never share your private key with anyone. Don’t tell me, don’t tell “customer service,” no one at all.
It’s like the key to your house—only you should hold it. We’ll cover the rest of the knowledge gradually.

Simply put: It’s like moving a crowded street party into a fast underground tunnel.
Layer 2 is built on top of the main chain, processing transactions in batches, and only sending back a final result.
Less congestion, lower fees, and unchanged security.
Without disrupting the underlying mechanism, this is currently the most practical solution.

You must have heard the legend: someone clicked their mouse three times and ended up with a luxury house. But what exactly is 'interaction'? It's not just a simple transaction; it's about deeply engaging with protocols, similar to using your favorite 'lazy' software. Exchanging, depositing coins, borrowing, minting NFTs – in short, it makes the network think you're a genuine enthusiast rather than a bot.
Why are '羊毛党' so obsessed? Because project teams reward early users. It's like getting a VIP pass for showing up before the party gets popular. The cost is the Gas fee, but if the project team issues a 'retroactive airdrop,' that’s the thrill of getting rich quick.

Think your crypto transactions are private? Think again. Your wallet is a glass house on a public street.
Every single trade, transfer, and approval you've ever made is permanently recorded on the blockchain. Tools like Etherscan and DexScreener turn this data into a public "detective manual."
Anyone can:
See your balance in real-time.
Track which coins you bought and sold.
Watch which protocols you interact with.

You're about to interact with a new DeFi application. You click 'Authorize.' Done. But what exactly just happened?
When you 'authorize' a token, you're not just approving that single transaction – you're giving that smart contract a 'permission slip' to move that specific token on your behalf.
Here's the scary part: Some contracts request unlimited authorization. This means that if the dApp is malicious or gets hacked, attackers can drain all of that token from your wallet. Not just the amount you intended to trade – but all of it.
Best practice? Regularly check your authorizations using tools like Revoke.cash. Look for contracts that only request exact amounts rather than 'unlimited' access. Think of it like a valet parking ticket: you want them to park your car, not keep a spare key forever.

We all love stablecoins because they allow us to avoid the extreme volatility of the cryptocurrency market. But not all 'stability' is created equal! You can think of them as different types of wallets.
$Tether (USDT.CC)$ It’s like a bank check – widely accepted, but you have to trust that the bank actually holds enough reserves.
$USDCoin (USDC.CC)$ It’s more like a digital receipt. Issued by regulated companies and subject to regular audits to prove that each coin is backed by real US dollars.
$Dai (DAI.CC)$ This one is native to the crypto world. It’s like an automatic balancing scale on the blockchain, maintaining its peg to the dollar through code and collateral, with no traditional corporate entity behind it.
So when you hold a stablecoin, are you trusting a company, an auditing firm, or simply the code?

You clicked the "Stake" button and then watched the rewards come in. It feels like free money, right? 🤑 But before you treat it like a high-yield savings account, let's take a look at the details. When you stake, you're not just "lending" your coins; you usually agree to a lock-up period. This means that if the market crashes, your funds could be stuck while others are panic selling (or buying the dip).
You are also voting for the network upgrade. If you don't run your own node, you are delegating your voting rights to the validators. Are they environmentally friendly? Do they support problematic proposals? You just agreed to let them speak on your behalf. 🤔
Staking is powerful, but it is a commitment. You are becoming an active participant in cybersecurity, rather than just a passive observer.

Projects shouting the 'decentralization' slogan are everywhere, but do you really know how to differentiate them? Don't get swayed by marketing jargon—these three methods will help you quickly assess:
First, check governance rights: A real DAO is not just a 'shareholder voting show.' Investigate whether proposals are initiated by the community, if the core team holds veto power, and who controls the code upgrade rights.
Second, examine asset control: Are your assets truly under your control (non-custodial wallet), or are they actually locked in the project's multi-signature wallet? True decentralization won't ask you to 'trust' any intermediaries.
Third, evaluate technical transparency: Open-source code is just the baseline. The key is whether network nodes can freely participate, data is censorship-resistant, and protocols can be invoked without permission.
The next time you encounter a new project, don't just look at the white paper—apply these three criteria, and the fox's tail will be revealed.

This article is dedicated to 'those in the crypto circle who do not make a living from trading'
First, we all agree that Bitcoin is good and holding it feels comfortable
Second, we all believe that Bitcoin will rebound in the medium to long term — buying at the peak might lock you in for four years, but buying gold at its peak could lock you in for fifty years
So the most important question is: how to accumulate more Bitcoin during a bear market?
Why not trade Bitcoin in waves?
@Sea_BitcoinA friend explained a concept to me:
Assume you successfully exited at $120,000 with 10 Bitcoins, now holding a lot of cash (U), feeling great — you can now buy 20 Bitcoins
If Bitcoin falls to $40,000, and you're still holding cash (U), then you could buy 30 Bitcoins, which feels even better, so you hold your cash (U) waiting for Bitcoin to drop further
But Bitcoin rebounds, say to $50,000, and you realize you can only buy 24 Bitcoins now, so you think about waiting a little longer to buy
Then Bitcoin rises again, rebounding to $60,000, and you find you've 'lost' the chance to buy 4 more Bitcoins, which feels terrible
When Bitcoin returns to $100,000, you are no longer able to buy, stuck in the pain of not having bought at the bottom
Then Bitcoin surges to $150,000, and you can never buy Bitcoin back!
How to accumulate more Bitcoin in a bear market?
First, don't go all-in
In 'Hoarding Bitcoin,' the Nine Gods advises that even if you are bullish on Bitcoin, don't let your position exceed 30% of your total assets
This article was written eight years ago. The Nine Gods entered the space in 2013, and now Bitcoin's volatility...
