Cryptocurrency is a digital currency that uses cryptography to secure transactions. The most well-known is Bitcoin (BTC), created in 2009. Unlike regular money, cryptocurrencies are decentralized — no bank or government controls them.

For beginners, Binance or KuCoin are the best options. Binance is the world's largest exchange with extensive educational materials. KuCoin offers a simple interface and a wide selection of coins. Take our exchange quiz for a personalized recommendation.

You can start with any amount — even $10-20. Most exchanges have no minimum deposit. However, we recommend starting with an amount you can afford to lose, as the crypto market is highly volatile.

Large exchanges (Binance, KuCoin) have strong security, but for large amounts it's better to use a hardware wallet (Ledger, Trezor). Always enable two-factor authentication (2FA) on your exchange account.

The Fear & Greed Index shows crypto market sentiment from 0 (extreme fear) to 100 (extreme greed). When the index is low, the market is panicking and there may be good buying opportunities. When high, it's wise to be cautious.

Staking is earning from cryptocurrency without active trading. You lock your coins for a period of time and receive interest (usually 5-20% annually). Available on most major exchanges.

Tax rules vary by country. In most jurisdictions, crypto gains are taxable as investment income. We recommend consulting a tax professional for specific advice in your country.

DeFi (Decentralized Finance) refers to financial services on the blockchain without intermediaries. It includes decentralized exchanges (DEX), lending, staking, and yield farming. More risky than centralized exchanges but potentially more profitable.

1) Enable 2FA (Google Authenticator). 2) Use a unique complex password. 3) Don't click suspicious links. 4) Enable anti-phishing codes. 5) Never share your wallet seed phrase with anyone.

Halving is an event where the miner reward per block is cut in half. It happens approximately every 4 years. After halving, the supply of new Bitcoin decreases, which historically has led to price increases.
