1. Core Concept Literacy: Understand these 3 logics to save 90% on tuition fees
1. The Three Layers of Digital Currency Essence
- Store of Value Layer: BTC = Digital Gold, total supply capped at 21 million, anti-inflation properties attract institutional allocation (Grayscale holds 630,000 BTC)
- Ecological Platform Layer: ETH = Blockchain Operating System, 90% of DeFi/NFT projects are developed based on ETH, 2.0 upgrade improves throughput by 1000 times
- Application Tool Layer: SOL/AVAX = High-performance Public Chains, 3000 TPS transaction speed + 0.0002 UGas fee, becoming the preferred chain for GameFi

2. The Unconventional Truths of Blockchain
- Decentralization ≠ No Regulation: 51% of Bitcoin's network hash power is controlled by mining farms in China and the US, the top 10 Ethereum 2.0 validators account for 35%
- Immutability ≠ Absolute Security: In 2023, on-chain phishing attacks resulted in losses exceeding $1.2 billion, and private key leaks are the cause of 99% of asset losses


2. Practical Strategies: The Path from 1000 U to 100,000 U
1. Golden Rule of Fund Allocation


2. Three Indicators for Trend Judgment
- Moving Average System: BTC must stabilize above the 200-week moving average (currently 92,000 U) to be considered a true bull market; falling below indicates a bear market
- Fear Index: Below 20 is a buying opportunity (in November 2024, the index was 18, BTC rose from 15,000 to 110,000)
- Exchange Traffic: Coinbase's new users have increased for three consecutive weeks by >10%, indicating institutional entry


3. Lessons from Heavy Losses: 5 Pitfalls 90% of Beginners Encounter
1. Misconceptions in Exchange Selection
- ❌ Wrong: Choosing small platforms for lower fees (a certain exchange went bankrupt in 2023, causing users to lose 200,000 U)
- ✅ Right: Only choose the three major exchanges (Binance/OKX/Huobi), and check the platform's cold wallet reserves (visible on the platform homepage)

2. Fatal Mistakes in Private Key Management
- ❌ Wrong: Storing private keys in WeChat/email (a player lost 500,000 U after their phone was stolen and 12 English words were cracked)
- ✅ Right: Write down 3 copies, hide them separately at home, parents' house, and bank safe deposit box, and never connect to the internet


4. Old Jiu's Private Tool Kit
1. Data Monitoring:
- DeFiLlama: See the locked positions on various chains (to judge fund flow)
- Glassnode: Check the movements of BTC whale addresses (to identify major operations)

2. Security Protection:
- Hardware Wallet: Ledger Nano X (physically isolates hackers)
- Anti-Phishing Plugin: MetaMask official plugin (to avoid entering fake websites)


5. Final Reminder
The crypto circle is not a casino; it is a battlefield for cognitive realization. Spend 3 months learning first (recommended books: 'Digital Gold', 'Blockchain Revolution'), then use 10% of your funds for practical operations—remember: 90% of those who made money in the 2021 bull market endured the 2018 bear market.
