$BTC Welcome! Bitcoin (BTC) is the first decentralized digital currency in the world, created in 2009 by an unknown person or group under the pseudonym "Satoshi Nakamoto". It relies on blockchain technology, which is a public and distributed ledger that securely and transparently records all transactions without the need for a central authority like banks.

Bitcoin is characterized by significant price volatility and has sparked widespread debate about its value and future uses. Some consider it a store of value and an investment asset, while others see it as an economic bubble. Despite this, Bitcoin remains widely popular and is used for online transactions and traded on many exchanges around the world.
