1. Cryptocurrency = the 'gold + cash + tool' of the digital world.
1. BTC: The hard currency of the crypto circle, equivalent to digital gold.
- Market cap percentage has been over 40% for years, fluctuations are 50% less than altcoins, drops less in bear markets, and rises steadily in bull markets.
- Holding logic: Accumulate coins in anticipation of halving cycles, a wealth creation movement that happens every 4 years (after the 2024 halving, it has risen by 300%).

2. ETH: The iOS system of the crypto circle, a universal application development platform.
- 90% of DeFi (decentralized finance) and NFT projects run on the ETH chain.
- Holding logic: Betting on the development of the blockchain ecosystem, with a 100-fold increase in throughput expected after the upgrade to 2.0 in 2025.

3. USDT: The cash of the crypto circle, an essential tool for survival.
- 1 USDT is always ≈ 1 USD; during crashes, it helps protect the principal (during the LUNA crash in 2022, those holding USDT lost 80% less).
- Usage: Exchange for USDT before a big drop, then buy back during the rebound, essentially insuring your assets.


2. Exchanges = the Taobao of the crypto circle, but choosing the wrong platform = money down the drain.
3 major safety islands that beginners must adhere to.

Warning: Never touch small platforms.
- A certain F exchange went bankrupt in 2023, users were unable to withdraw their funds, and 200,000 USDT went down the drain.
- Criteria: Must have a US MSB license + cold wallet reserve disclosure (can be found on the platform homepage).


3. Wallet = a digital piggy bank, but using the wrong key = bankruptcy.
The life-or-death choice between two types of wallets.
1. Exchange wallet (beginner's first choice).
- Like storing in Alipay, the platform manages your private key, and you can use it after registering an account.
- Disadvantage: If the platform goes bankrupt, you're done (refer to the FTX bankruptcy incident).

2. Personal wallet (a must for experienced players).
- Wallets like MetaMask require you to save 12 English words (private key) yourself.
- Terrifying case: A player stored their private key in WeChat notes; after their phone was stolen, 500,000 USDT was instantly wiped out.

Beginner's rule: Earn at least 10,000 USDT before touching a personal wallet.
- For the first 3 months, only operate on exchanges. After familiarizing with the process, transfer 30% of assets to a personal wallet.
- Private key storage method: Write down 3 copies and hide them in your home, your parents' home, and a bank safe.


Old Jiu's ultimate reminder: 3 actions to help you lose 50% less.
1. Never invest all your money into coins; keep 30% in USDT (cash is king).
2. Check the market cap before new coins launch; avoid those under 100 million USD (90% are scams).
3. When someone shouts a trade signal, immediately open the FOMO detector:
- Did someone suddenly post a screenshot of 100 times returns in the group? → Likely a scam.
- If the project team doesn't even have a Chinese version of the white paper? → Run away immediately.
