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.
The price of bitcoin stands at $434, well below the high of $1,216 it reached in late 2013. But itâs not the price that matters. What matters is whether people are using bitcoin, and more than ever, they are. Check out the graph below, which shows the number of daily bitcoin transactions.
