What is cryptocurrency?

Cryptocurrency (Crypto) is a type of digital asset based on blockchain technology, such as Bitcoin (BTC) and Ethereum (ETH). Its characteristics include decentralization—there is no control from banks or governments, and all transaction records are publicly transparent and immutable.

Common Terminology

Blockchain: A distributed database, like a globally shared ledger. Wallet: A tool for storing crypto assets (divided into cold/hot wallets, with different levels of security).

DeFi: Decentralized financial services, such as lending and trading, without the need for traditional banks.

Risk Awareness

Cryptocurrency prices are highly volatile and can skyrocket or plummet in a short period.

There are significant differences in global regulatory policies, and some countries prohibit related transactions (you need to understand local regulations on your own).

Be sure to keep your private keys safe! Losing your private key = permanently losing your assets.

Technical Knowledge

The total supply of Bitcoin is 21 million coins, generated through 'mining'.

Ethereum supports smart contracts and is the underlying platform for many applications.
