Question 1

What is cryptocurrency and how does it work?

Accepted Answer

Cryptocurrency is a digital form of money that uses cryptography to secure transactions on a decentralised network called a blockchain. Unlike traditional currencies issued by governments, cryptocurrencies operate without a central authority. Bitcoin, created in 2009, was the first cryptocurrency. Since then, thousands more have been created — each with different purposes, technologies, and use cases. Our beginner guide explains the full picture in plain English.

Question 2

What is Bitcoin and why does it have value?

Accepted Answer

Bitcoin (BTC) is the original cryptocurrency, launched in 2009 by a pseudonymous creator known as Satoshi Nakamoto. Its value comes from a combination of scarcity (only 21 million BTC will ever exist), decentralisation (no single person or government controls it), security (backed by the world's most powerful computing network), and growing adoption as a store of value. Think of it as digital gold — difficult to produce, easy to transfer, and impossible to counterfeit.

Question 3

What is Ethereum and how is it different from Bitcoin?

Accepted Answer

Ethereum is a blockchain platform launched in 2015 that supports programmable "smart contracts" and decentralised applications (dApps). While Bitcoin is primarily a store of value and payment system, Ethereum is a programmable platform that powers DeFi protocols, NFTs, and thousands of decentralised applications. Ether (ETH) is the native currency used to pay for transactions and computations on the Ethereum network.

Question 4

How do I safely store cryptocurrency?

Accepted Answer

The safest way to store crypto is in a wallet where only you control the private keys. There are two main types: hot wallets (connected to the internet — convenient but slightly more vulnerable, e.g. MetaMask, Trust Wallet) and cold wallets (offline hardware devices — most secure, e.g. Ledger, Trezor). Never store large amounts on an exchange long-term, always write down your seed phrase on paper (never digitally), and enable two-factor authentication everywhere. Our wallets guide covers all of this in detail.

Question 5

What is DeFi (Decentralised Finance)?

Accepted Answer

DeFi refers to financial services built on public blockchains that operate without traditional intermediaries like banks. Using smart contracts, DeFi protocols allow anyone to lend, borrow, trade, earn interest, and more — all without a bank account or credit check. Major DeFi platforms include Uniswap, Aave, Compound, and MakerDAO. While DeFi offers exciting possibilities, it also carries significant risks including smart contract bugs and high volatility.

Question 6

Is cryptocurrency legal?

Accepted Answer

The legal status of cryptocurrency varies by country. In most Western nations (USA, UK, EU, Australia, Canada), cryptocurrency is legal to buy, sell, and hold. Some countries have banned it outright (e.g. China, Algeria). In most places, crypto profits are subject to capital gains tax. Always check the specific regulations in your country and consult a financial or legal professional for tax advice. FaucetNova does not provide legal or financial advice.

Question 7

How do I get started with cryptocurrency?

Accepted Answer

Start by educating yourself before putting any money in. Read our beginner guides on Bitcoin and Ethereum. Then choose a reputable exchange (Coinbase, Kraken, or Binance are popular options), create an account, complete identity verification, and make your first small purchase. Set up a personal wallet to move your crypto off the exchange. Start small, diversify, and never invest more than you can afford to lose entirely.

Question 8

What is a blockchain and how does it work?

Accepted Answer

A blockchain is a distributed database that stores records in "blocks" linked together in a chronological "chain." Each block contains a batch of transactions and a cryptographic reference to the block before it, making it nearly impossible to alter historical records. The database is maintained by thousands of independent computers (nodes) around the world — so there is no single point of failure or control. This architecture is what makes cryptocurrencies trustless and censorship-resistant.

Question 9

What are crypto scams and how do I avoid them?

Accepted Answer

The most common crypto scams are: rug pulls (fake projects that disappear with investor funds), phishing (fake websites or emails that steal your login credentials), fake giveaways ("send 1 BTC, get 2 back" — always a scam), pump-and-dump schemes, and fake customer support impersonators. Golden rules: never share your seed phrase with anyone, ever; verify URLs carefully before entering credentials; be deeply sceptical of any guaranteed returns; and use hardware wallets for large amounts.

Question 10

What is the difference between proof of work and proof of stake?

Accepted Answer

These are two different ways a blockchain network reaches consensus (agreement) on the valid state of the ledger. Proof of Work (PoW), used by Bitcoin, requires miners to solve complex mathematical puzzles using computational energy — it is secure but energy-intensive. Proof of Stake (PoS), used by Ethereum since "The Merge" in 2022, requires validators to lock up ("stake") crypto as collateral — it is far more energy-efficient. Both achieve the same goal: securing the network from fraud without a central authority.
