Getting started
What is cryptocurrency in simple terms?
Digital money that runs on a public, decentralized network instead of through a bank. Ownership is tracked on a shared ledger called a blockchain, secured by cryptography. Full explanation: What is cryptocurrency?
Is crypto safe?
The blockchain itself is very secure, but prices are volatile and scams are common. The real risks are losing your keys, phishing, and market swings - all manageable with good habits. See security best practices.
Do I need a lot of money to start?
No. Coins are divisible, so you can start with $10-50. Starting small while you learn is exactly the right approach.
How do I buy my first crypto?
Pick a reputable exchange, verify your identity, deposit by bank transfer or card, and place a simple market order. Step-by-step walkthrough: How to buy your first crypto. Trusted exchanges are listed in our resources hub.
Can I buy a fraction of a Bitcoin?
Yes. Each bitcoin divides into 100 million units (satoshis), so you can buy any amount - even $10 worth.
Wallets & security
Where should I store my crypto?
Small, active amounts: a reputable exchange or hot wallet is fine. Larger long-term holdings: a hardware (cold) wallet that keeps your keys offline. Compare options in wallets explained.
What is a seed phrase?
A list of 12-24 ordinary words that can restore your entire wallet. It effectively IS your money: store it offline (paper or metal), never photograph it, and never type it into any website.
What happens if I lose my private keys?
If you self-custody and lose both the device and the seed phrase backup, the funds are gone permanently. No support line can recover them - that is the trade-off of being your own bank.
How do I avoid scams?
Never share your seed phrase, verify the exact URL before logging in, ignore "guaranteed returns" and unsolicited DMs, and turn on two-factor authentication everywhere. Full checklist: security guide.
Are crypto transactions reversible?
Generally no - once confirmed, a transaction is final. Always double-check the address (and send a small test amount first for large transfers).
Money matters
Do I pay taxes on crypto?
In many countries, selling, trading and earning crypto are taxable events, while buying and holding usually is not. Rules vary a lot by country - keep records and consult a local professional. Primer: crypto taxes basics.
What fees will I pay when trading?
Three kinds: the exchange's trading fee (often 0.1-1.5% per trade), possible deposit/withdrawal fees, and network fees when you move coins on-chain. Always read the fee page before trading.
What is the difference between Bitcoin and Ethereum?
Bitcoin is scarce digital money - a store of value. Ethereum is a programmable platform that runs smart contracts and powers DeFi, NFTs and tokens. Deep dive: Bitcoin vs Ethereum.
Is Coinveo a real exchange?
No - Coinveo is a design demo built for education. The market data is real (CoinGecko and Binance public APIs), but there are no accounts, no trading and no custody here. Nothing on this site is financial advice.
