The History of Bitcoin

In late 2008, a person or group using the pseudonym Satoshi Nakamoto published a white paper on bitcoin, explaining how the cryptocurrency would work.
After that in 2009, Nakomoto mined the first-ever bitcoin, known as the genesis block.

In may 2010, a programmer from Florida named Laszlo Hanyecz offered 10,000 bitcoins in exchange for two pizzas. This is believed to be the first time BTC was used to make a purchase and celebrated as Bitcoin Pizza Day.

In 2011, Ross Ulbricht has founded an online dark-web marketplace dubbed Silk Road, who ran the site using the pseudonym Dread Pirate Roberts. He wanted SilkRoad to grow into a force to be reckoned with that can challenge the power that is and at last give people the option to choose freedom over tyranny.

After that in March 2013, the value of Bitcoins hit $1 billion in circulation and started attracting the attention of Silicon Valley and venture capitalists. Bitcoin stagnated for several years after 2013. But in 2017, the end of the year sees a huge price peak, coming close to $20,000 in Bitcoin value as shown in graph(below).

How Bitcoin Works

Bitcoin concept might be quite complex: it isn’t only a digital currency, but a decentralized network. That means there is no central server, BTC is a peer-to-peer network. Bitcoin ledger is distributed or public, you can store it on your computer.

Each bitcoin is basically a computer file which is stored in a cryptocurrency wallet app on a smart device such as a smartphone and computer. you can send Bitcoins to your BTC crypto wallet and to other people. These transactions are recorded in a public list called the Blockchain which requires an electronic signature, is supported by a proof-of-work protocol to provide the security and allow only legitimate transactions.

A blockchain is used to generate new BTC and verify the ones that are transferred from one user to another. These transactions are irreversible, and the pseudonymous public ledger the transactions are made on giving it a level of transparency other financial system doesn’t offer.


The advanced explanation:

The technical side of Bitcoin working is a bit more complex. Each new transactions are recorded an verified onto a new block of data in the blockchain and each block in the chain includes cryptological code linking to it.

These transactions are highly secure due to the cryptography at every step in the process, which can take quite a lot of time to verify.

However, there is a possibility to steal bitcoins by discovering someone’s digital wallet and the password. So it is highly recommended to secure your Bitcoin wallet.

In order to buy or sell Bitcoins, you’ll need a Bitcoin wallet to store them in. There are many types of cryptocurrency wallets available such as software and hardware wallets.

How do people get Bitcoins?

If you want to get a substantial amount of bitcoins fast, you need to spend money buying them, or if you want to get bitcoins for free, you need to spend a lot of time earning them.


There are three main ways to get Bitcoins.

  • Buy Bitcoins using fiat money.
  • Sell things and let people pay you with Bitcoin.
  • Create Bitcoins using computational power (Bitcoin mining).

Bitcoin Mining

Collecting Bitcoins can be boiled down to a simple premise: miners, as they are known, purchase powerful computing chips designed for the process an use them to run specifically crafted software day and night.

That software forces the system to complete complex encrypted calculations- imagine them digging through layers of digital rock. If all goes to plan, the miners are rewarded with some Bitcoins at the end of the process. To learn how to mine Bitcoins, read our complete guide on Bitcoin mining.

Buying and Selling Bitcoin

It is entirely possible to both buy and sell Bitcoins. Buying Bitcoins is quite easier than mine Bitcoins because there are many BTC exchanges that allow you to purchase bitcoins using your credit/debit card or PayPal.
