The IgarapÃ© Bahia gold deposit has developed from weathering of a near-vertical hydrothermal Cu (Au) mineralization zone. The unweathered bedrock composed of chlorite schists is mainly metamorphosed basalts, pyroclastic and clastic sedimentary rocks and iron formation.
So what exactly is Bitcoin? Bitcoin is a digital currency and digital payment system that allows people to send and receive Bitcoins â or digital tokens â to anyone, anywhere in the world. It runs on a decentralized network of computers in which all transactions are recorded, verified and updated by technology known as blockchain, which is akin to an online public ledger.
Bitcoin is the first global, decentralized currency that allows you to send money from one person to another without involving a third party broker, such as a bank. You only need your computer to make transactions because Bitcoin is fundamentally software. As a decentralized currency, Bitcoin isnât controlled by anyone.
