What is Bitcoin?

Digital Money

Money for the internet age

Bitcoin is digital money that works without banks. You can send it to anyone, anywhere in the world, at any time — just like sending an email, but with value attached.

It was created in 2009 by someone using the name Satoshi Nakamoto. Unlike dollars or euros, no government or company controls Bitcoin. It runs on a network of computers around the world that anyone can participate in.

  • It's digital — it exists only on the internet, like your bank balance
  • It's limited — only 21 million will ever exist (like digital gold)
  • It's open — anyone can use it, no permission needed
  • It's global — works the same in every country

Why do people use Bitcoin?

There are many reasons people choose Bitcoin. Here are the most common ones.

🔒

You own it — truly

No bank can freeze your account or tell you what to do with your own money. Bitcoin gives you direct control.

🌎

Send money anywhere

Send value to anyone in the world in minutes, not days. No forms, no intermediaries, no business hours.

📈

Limited supply

Only 21 million will ever exist. Many see this scarcity as protection against inflation.

👀

Transparent system

Every transaction is recorded on a public ledger. The rules are clear and can't be changed by any single entity.

Low-cost transfers

Much cheaper than wire transfers, especially internationally. Layer 2 makes small payments nearly free.

👥

Financial access

Billions lack banking access. Bitcoin only requires an internet connection.

Common questions

Honest answers to the things beginners ask most.

The Bitcoin network itself has never been hacked and is secured by enormous computing power. However, like cash, you need to keep it safe. Use reputable wallets, enable security features, and never share your private keys. The most common risks come from user mistakes or scams, not from the technology itself.

People have asked this at every price point since Bitcoin was worth $1. Whether it's "too late" depends on your goals and time horizon. Many believe Bitcoin adoption is still early. Remember, you don't need to buy a whole Bitcoin — you can start with any amount, even a few dollars.

No! Bitcoin is divisible to eight decimal places. The smallest unit is called a "satoshi" (or "sat"), and one Bitcoin equals 100 million sats. You can buy as little as a few dollars' worth. Most people own fractions of a Bitcoin.

Bitcoin is legal in most countries, including the United States, Canada, the EU, Japan, and many others. Some countries have restrictions. El Salvador even made it legal tender. Check the regulations in your specific country, as rules vary and can change.

Bitcoin mining does use electricity, and this is a legitimate concern. However, the industry is increasingly powered by renewable energy, and some miners use energy that would otherwise be wasted. The debate is ongoing, and it's worth looking at the nuances rather than just headlines.

Bitcoin was the first cryptocurrency and remains the largest by far. It has the longest track record, the most security, and the most decentralized network. Other cryptocurrencies ("altcoins") often have different goals or trade-offs. Many Bitcoin advocates focus exclusively on Bitcoin for its proven reliability.

If you lose access to your private keys (or seed phrase) and have no backup, your Bitcoin becomes inaccessible. This is why proper backup is essential. Write down your recovery phrase, store it safely offline, and consider using a hardware wallet for larger amounts.
