    Bitcoin and cryptocurrency are words that over the past two years, have crept slowly but steadily into our vocabulary.

    While the whole concept of Cryptocurrency (Crypto for short) and Bitcoin (otherwise BTC) isn’t new to some reading this,to other people, it is a new concept. This article, therefore aims to break down the information about bitcoin into easy to understand terms.

    What is Bitcoin?

    Bitcoin is a form of cryptocurrency. Cryptocurrency isn’t some physical form of coin or currency you can keep in your wallet. Rather, cryptocurrency, and by extension, Bitcoin is basically a line of code (as in programming) with value; which can be purchased and sold for money.

    Created by Satoshi Nakamoto in early 2009,  Bitcoin was created out of the desire and thought of having a decentralized currency — money that no authority, company, or individual had control over and owners of the currency could not be traced or identified.


    Like physical currency where you keep your money in your pockets, purse or a wallet, a “Bitcoin Wallet” is a special program that allows you store your Bitcoin and also, transfer to other users, a merchant or customer that accepts Bitcoin as a form of payment; picture it as removing a couple of Naira or dollar note from your purse to give to another person.

    Transfer of Bitcoin is safe, reliable and remain completely anonymous as it is a form of digital money that uses encryption to secure transactions. This same encryption guides the creation of new units.


    How do I mine (create) Bitcoin?

    Well, it would surprise you to know that mining Bitcoin is  free. However, the resources and the know-how you need to possess to mine the virtual currency might cost you. Before moving to the mining of the currency, there are some facts that need to be stated forehand:

    • Only 12.5 Bitcoin can be mined / created every 10 minutes.
    • There are finite Bitcoin — there can only be 21 million Bitcoin in existence.
    • The creator, Satoshi Nakamoto, is believed to own 1 million of Bitcoin
    • In July 2017, the total amount of Bitcoin in circulation were believed to be about 16.4 million.
    • By 2041, the 21 million cap on Bitcoin quantity is estimated to be reached.

    The above being said. Mining Bitcoin is a complex, capital and energy-intensive process as it requires sophisticated hardware, constant power (electricity) and internet. Presently, there are thousands of miners actively mining Bitcoin and all they do is to compete solve a complex mathematical puzzle within the space of 10 minutes.

    The fastest miner to successfully solve the puzzle gets rewarded with 12.5 Bitcoin (currently worth over 100,000 USD). Miners make money by selling newly generated coin to interested buyers.

    How do I Buy or Sell Bitcoin?

    Generally, to buy or sell Bitcoin, you have to have a wallet and be registered on platforms where Bitcoin are bought and sold. These Bitcoin sales and purchase websites are known as Bitcoin Exchanges.

    The volume of Bitcoin you intend to buy or sell determines the type of buyer you are. And the type of buyer you are determines the type of Exchange you use. Exchanges like Gemini and GDAX deal with buyers and sellers of large volume of Bitcoin.

    CoinbaseKrakenBitstamp are trusted exchange for trading smaller volumes of Bitcoin. In Africa, you can buy or sell on Bitkoin Africa.

    It is noteworthy to state that security and trust is a big factor to consider when choosing Exchange platforms to trade your Bitcoin. Back in 2016, Bitcoin worth millions of dollars we’re stolen when Bitfinex, a Bitcoin Exchange platform was hacked.
