Bitcoin (BTC)

Digital gold. The currency the internet chose.

What is Bitcoin?

Bitcoin is the first and largest cryptocurrency by market capitalization. It introduced the idea that money could exist without banks, governments, or any central authority. Instead of trusting an institution, Bitcoin trusts mathematics — every transaction is verified by a global network of computers following a shared set of rules.

With a hard cap of 21 million coins that will ever exist, Bitcoin is fundamentally scarce. That scarcity, combined with growing global adoption, has made it the most recognized store of value in the digital asset space. Institutions, sovereign wealth funds, and individual investors all hold Bitcoin as a hedge against currency debasement.

Beyond holding value, Bitcoin serves as a censorship-resistant payment rail. Anyone with an internet connection can send any amount of value to anyone else, anywhere in the world, without permission. Settlement is final within minutes, not days.

How Bitcoin Works

Think of Bitcoin as a shared spreadsheet that everyone in the world can read, but nobody can cheat on. When you send Bitcoin to someone, that transaction gets announced to thousands of computers around the globe. Those computers race to bundle transactions together into a "block" — and the winner gets to add that block to the permanent record (the blockchain). Because everyone has a copy of this record, nobody can fake a transaction or spend the same coin twice.

Team & Development

Bitcoin was created by the pseudonymous Satoshi Nakamoto, who published the whitepaper in 2008 and released the software in 2009. Satoshi stepped away from the project in 2011. Today, Bitcoin is maintained by hundreds of open-source contributors worldwide, with no single company or foundation in control.

Frequently Asked Questions

How much Bitcoin do I need to buy to get started?

You can start with as little as $50. Bitcoin is divisible to 8 decimal places (the smallest unit is called a satoshi), so you never need to buy a whole coin.

Where do I store Bitcoin after buying?

In a Bitcoin wallet. Software wallets like Exodus or BlueWallet work for smaller amounts. For larger holdings, a hardware wallet like Ledger provides stronger security by keeping your keys offline.

Why does the Bitcoin price fluctuate so much?

Bitcoin trades 24/7 on global markets. Price swings come from shifts in demand, macroeconomic events, regulatory news, and overall market sentiment. Volatility tends to decrease over longer time horizons as adoption grows.

Is Bitcoin environmentally friendly?

Bitcoin mining uses significant energy, but an increasing share comes from renewable sources. The network incentivizes miners to seek the cheapest electricity, which is often stranded or surplus renewable energy. The debate around energy use continues to evolve alongside the industry.
