Cryptocurrencies are a decentralized form of digital currencies. They run on encryption technology, which means no single entity controls the currency. To prevent counterfeiting, tokens are cryptographically sealed and cannot be tampered with after they're created. These tokens can take many forms, and they are all built over encrypted blockchain technology, which is a virtual and anonymous public ledger that records every transaction using one of these tokens. Bitcoins have become a type of cryptocurrency, a form of digital currency that uses cryptography for security. Bitcoins are not issued by central banks or governments, nor are individual bitcoins valuable as a commodity in themselves. Instead, they have value only in what people will pay for them.
