Bitcoin (BTC) is the world’s first widely-adopted cryptocurrency. Bitcoin uses cryptographic methods to create a digital currency that is decentralized and not controlled by any single entity. The Bitcoin network facilitates permissionless and secure peer-to-peer transactions on the internet. Every transaction involving BTC is recorded on the network’s blockchain, which is essentially a distributed, immutable, open-source ledger that records every transaction ever made using Bitcoin.
The supply of Bitcoin is capped at 21 million BTC, meaning that supply of BTC cannot be inflated or manipulated in any way.
