Buy Bitcoin

Bitcoin (BTC) is the world’s first and largest decentralised cryptocurrency. It operates as digital money that works without a central bank or financial institution in the middle.

Instead of a bank keeping track of balances, Bitcoin runs on a secure, public network. Every transaction is permanently recorded on a shared digital ledger called the blockchain, which is maintained collectively by thousands of computers worldwide. Launched in January 2009, Bitcoin allows anyone in Ireland and globally to send value directly to another person over the internet, peer-to-peer, with no intermediary required.

What is Bitcoin used for?

While originally built as an electronic cash system, Bitcoin’s primary use case today is as a digital store of value, increasingly viewed as "digital gold."

When you purchase or send Bitcoin, your transaction is broadcast across a global network of computers that verify and secure it. Think of it like a stock settlement, but instead of a central clearinghouse, an independent network does the work to ensure the record is permanent and public.

This tamper-resistant network makes Bitcoin highly secure. Furthermore, unlike fiat currencies (like the Euro) or traditional stocks, Bitcoin has absolute scarcity. Its total supply is hard-capped at 21 million coins. No government or central bank can print more, making it a popular hedge against inflation for people looking to diversify their investment portfolios.

The history of Bitcoin

Bitcoin was introduced to the world in October 2008 through a white paper titled Bitcoin: A Peer-to-Peer Electronic Cash System. It was published under the pseudonym Satoshi Nakamoto, an anonymous creator whose real identity remains unconfirmed to this day.

The live network officially launched on 3 January 2009. Embedded into the historic first block of data (the "Genesis Block") was a message: "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks". This served as both a permanent timestamp and a direct critique of the centralised banking systems Bitcoin was designed to bypass.

New coins enter circulation via a process called crypto mining, which follows a fixed, mathematical schedule that slows down over time. This built-in scarcity means that as demand to buy Bitcoin increases, the fixed supply cannot expand to meet it. The idea is simple scarcity: the slower new supply comes in, the more existing coins are worth, assuming demand holds.
