It is the first decentralized digital currency in the world.
It does not belong to any government, bank, or company. It works thanks to thousands of computers around the planet that validate all transactions. Key points to understand: Bitcoin is digital money that you can send without intermediaries. It is limited to 21 million coins, which is why many consider it 'digital gold.'
No government prints it, so it cannot 'devalue' due to excess money. To use it, you only need a digital wallet.
