Bitcoin is a digital or virtual currency that uses peer-to-peer technology to facilitate instant payments. Bitcoin is decentralized, meaning it is not subject to government or financial institution control. The network is peer-to-peer and transactions take place between users directly, without an intermediary.
These transactions are verified by network nodes through the use of cryptography and recorded in a public distributed ledger called a blockchain. Bitcoin was invented by an unknown person or group of people under the pseudonym Satoshi Nakamoto and released as open-source software in 2009.
Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies, products, and services. As of February 2015, over 100,000 merchants and vendors accepted bitcoin as payment. Bitcoin can be bought on online exchanges and stored in a wallet.
The Mt. Gox exchange was the most popular bitcoin exchange at the time of its collapse in 2014.
In order to become a certified professional bitcoin, you must first complete an accredited bitcoin course. These courses are offered by various institutions and will teach you everything you need to know about bitcoins, including how to buy, sell, and trade them.
Once you have completed a course, you will then need to take an exam in order to receive your certification.
