Frequently asked questions

What is cryptocurrency? +

Cryptocurrency is a form of digital money secured by cryptography and running on a decentralised computer network. No single bank or government controls it. Bitcoin was the first, launched in 2009, and thousands of others have followed.

What is Bitcoin? +

Bitcoin is the world’s first cryptocurrency, created in 2009 by the pseudonymous Satoshi Nakamoto. It is a decentralised digital currency that allows peer-to-peer transactions without a bank. There will only ever be 21 million bitcoins in existence.

What is blockchain? +

A blockchain is a shared digital ledger that records transactions across a network of computers. No single person or organisation controls it. Once data is written to a block and added to the chain, it is extremely difficult to alter — making it transparent and tamper-resistant.

What is a private key? +

A private key is a unique string of letters and numbers that gives you access to your cryptocurrency. Think of it like a password that cannot be reset. Anyone who has your private key can access your funds — never share it with anyone.

Is crypto a good investment? +

This is not financial advice. Cryptocurrency is a high-risk asset class with significant price volatility. Before making any investment decision, conduct your own research, understand the risks, and consider consulting a licensed financial adviser.
