How Does Bitcoin Actually Work ?

In today’s digital and internet trapped world it is probably the inevitable thing that we should keep our money as safe as possible either in digital format or any other virtual existing state. And bitcoin is the new form you should must be knowing.

Bitcoin is a cryptocurrency (sometimes called virtual currency or digital currency). It’s a new type of money that’s totally virtual. It’s stored in a “digital wallet” application on computers and smartphones.

Instead of relying upon governments and financial institutions to create and manage it, Bitcoin relies upon a vast, decentralized network of computers used by individuals or groups (known as “miners”) to validate and keep track of transactions using cryptography and advanced mathematics.

The worldwide financial crisis of 2008 prompted the invention of Bitcoin by Satoshi Nakamoto. No one knows who Nakamoto is, but many people suspect it’s a pseudonym used by a group of programmers who created the fundamental technology underlying Bitcoin: the blockchain.

The blockchain is like a publicly-distributed ledger. It’s an ever-expanding computer file that contains the history of the creation of every Bitcoin in existence, as well as every Bitcoin transaction ever conducted.

As Bitcoins are created and transactions take place, they are made part of a collection of data known as a block. When a block is filled, it is added to the chain of blocks in sequential order after it has been validated by miners in the Bitcoin network.

Miners possess specialized computer equipment capable of performing the advanced mathematics and cryptography required to validate Bitcoin transactions. They compete to be the first to validate new blocks, because the winning miners are issued newly-created Bitcoins for their efforts. This is how new Bitcoins are created.

As new blocks are added, the blockchain is updated and relayed to all the computers (called nodes) in the Bitcoin network. This makes Bitcoin very secure, since hackers would have to break into nearly all nodes simultaneously to steal Bitcoins. Most experts consider this an impossible task.

When Bitcoin began, each Bitcoin was worth almost nothing. A lot has changed in the last decade. In 2017, Bitcoin hit an all-time high value of $19,783. The cryptocurrency is extremely volatile, though.

Its value quickly decreased to less than half its peak and continues to fluctuate wildly based upon numerous factors, including the fact that many countries are attempting to regulate or ban cryptocurrencies altogether.

However, Bitcoin might not suffer from devaluation in the future the way government-issued currency often does. When central governments print more money, the value of current money decreases.

More and more online stores are accepting Bitcoin as payment. You may never be able to pay your taxes with Bitcoin, however. Nevertheless, many people still find Bitcoin attractive because it’s not controlled by governments or banks and it allows transactions to be completely anonymous (as long as you don’t give out your Bitcoin wallet identification code!).

How do you get Bitcoins today? You can buy them with government-issued money. You can also sell things and ask people to pay you with Bitcoins. Finally, you can become a miner, although it’s difficult and expensive to acquire the technology needed to mine Bitcoins.
