What is Bitcoin?
O que é Bitcoin? is the world’s first widely-adopted cryptocurrency. It allows for secure, peer-to-peer transactions on the internet without the need for middlemen like banks. Instead, it relies on a technology called blockchain to ensure transparency and security.
Bitcoin was created (by a person or group who remains anonymous) during the global financial crisis of 2008, as a way to enable transactions without the need for trusted third parties, such as a bank. It has since become a medium of exchange, a store of value, and a unit of account, among other things.
Bitcoin Security: Protecting Your Assets in the Digital Realm
In its most basic form, Bitcoin is digital cash that you can send across the internet as easily as email or instant messaging. When someone sends you money in Bitcoin, it goes to a “virtual vault” that only you can access with your private key. The transaction is then recorded on the blockchain, which can’t be altered or destroyed.
Bitcoins can be bought with real money or earned by solving problems on the internet using specialized computers. People who process Bitcoin transactions are called miners and are rewarded with new coins for their work. Bitcoins can also be stored in a wallet that you create and keep on your computer. Although it doesn’t have the physical properties of gold, some people treat it like a commodity and invest in it hoping that its price will increase over time, similar to how stocks are traded. The quantity of Bitcoins is limited and finite, so the price will likely rise as demand increases.
