1. Cryptocurrency: A "Digital Revolution" Disrupting Traditional Currency
If you're still defining cryptocurrency as "virtual currency," you might be out of date.
The essence of cryptocurrency is digital assets "locked" with blockchain technology.
It doesn't require bank endorsement, nor does it rely on government credit—thousands of computers worldwide keep the ledger simultaneously, and once the data is on the blockchain, it cannot be altered and is fully transparent.
Bitcoin (BTC) is the "pioneering ancestor" of this revolution, with a total supply of 21 million making it "digital gold"; Ethereum (ETH) goes further, supporting a decentralized application (DApp) ecosystem with smart contracts, enabling everything from games to finance to "run on the chain."
2. The Two Big Players in the Cryptocurrency World: Bitcoin vs Ethereum
Bitcoin (BTC):
Satoshi Nakamoto's "decentralized experiment," now sits firmly at the top of the market cap.
Its value logic is simple: fixed supply, anti-inflation.
Institutions hoard it like gold, retail investors chase it as faith, and its price volatility can shake the global financial market.
Ethereum (ETH):
If Bitcoin is "digital gold," then Ethereum is the "blockchain operating system."
From DeFi (Decentralized Finance) to NFT (Digital Collectibles), ETH's ecosystem applications have long transcended the category of currency, becoming a common battlefield for "tech geeks" and "speculators."
3. Cryptocurrency Trading Models: From "Hodlers" to "Contract Experts"
Want to make money in the cryptocurrency world? Start by choosing the right "weapon":
Spot Trading:
The most basic way—buying coins with fiat currency or swapping one coin for another.
Suitable for "laid-back hodlers": long-term holding of Bitcoin and Ethereum, waiting for the bull market to "feast."
Margin Trading:
Using a small amount of capital to leverage a large position, amplifying gains (or losses).
Suitable for short-term players with a strong "gambling nature," but remember: Adding leverage = licking blood off a knife's edge, liquidation can happen
with just one K-line. Futures Trading:
The "futures market" of the cryptocurrency world, you can go long (buy) or short (sell).
Experts use it to "profit in bear markets," while beginners can "lose everything overnight."
(Warning: Beginners should proceed with caution! Learn technical analysis first, then talk about contracts)
