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.
âWeâre the backbone of the entire Bitcoin industry,â says KodriÄ, 25, whoâs wearing a black t-shirt with âZero Excusesâ in fluorescent green capital letters. âThe wallet services, ATM machines, mining companies all rely on us. The price of Bitcoin is the de facto price on Bitstamp. Weâre the to-go exchange.â. It may sound like bluster, but I hear the same thing when I talk to people in the wider Bitcoin community.
