CRYPTOCURRENCY

INTRODUCTION AND DEFINITION:
A cryptocurrency (or cryptocurrency) is a digital asset designed to work as a medium of exchange that uses strong cryptography to secure financial transactions, control the creation of additional units, and verify the transfer of assets.
Cryptocurrencies use decentralized control as opposed to centralized digital currency and central banking systems.
The decentralized control of each cryptocurrency works through distributed ledger technology, typically a blockchain, that serves as a public financial transaction database.
Bitcoin, first released as open-source software in 2009, is generally considered the first decentralized cryptocurrency.
Since the release of bitcoin, over 6,000 altcoins (alternative variants of bitcoin, or other cryptocurrencies) have been created.
According to Jan Lansky, a cryptocurrency is a system that meets six conditions:

1. The system does not require a central authority, its state is maintained through distributed consensus.
2. The system keeps an overview of cryptocurrency units and their ownership.
3. The system defines whether new cryptocurrency units can be created. If new cryptocurrency units can be created, the system defines the circumstances of their origin and how to determine the ownership of these new units.
4. Ownership of cryptocurrency units can be proved exclusively cryptographically.
5. The system allows transactions to be performed in which ownership of the cryptographic units is changed. A transaction statement can only be issued by an entity proving the current ownership of these units.
6. If two different instructions for changing the ownership of the same cryptographic units are simultaneously entered, the system performs at most one of them.

   HISTORY:
   Those who don’t learn from history are doomed to repeat its mistakes – so here is a brief history of Bitcoin and cryptocurrency.
   1998 – 2009 The pre-Bitcoin years
   Although Bitcoin was the first established cryptocurrency, there had been previous attempts at creating online currencies with ledgers secured by encryption. Two examples of these were B-Money and Bit Gold, which were formulated but never fully developed.
   2008 – The Mysterious Mr. Nakamoto
   A paper called Bitcoin – A Peer to Peer Electronic Cash System was posted to a mailing list discussion on cryptography. It was posted by someone calling themselves Satoshi Nakamoto, whose real identity remains a mystery to this day.
   2009 – Bitcoin begins
   The Bitcoin software is made available to the public for the first time and mining – the process through which new Bitcoins are created and transactions are recorded and verified on the blockchain – begins.
   2010 – Bitcoin is valued for the first time
   As it had never been traded, only mined, it was impossible to assign a monetary value to the units of the emerging cryptocurrency. In 2010, someone decided to sell theirs for the first time – swapping 10,000 of them for two pizzas. If the buyer had hung onto those Bitcoins, at today’s prices they would be worth more than $100 million.
   2011 – Rival cryptocurrencies emerge
   As Bitcoin increases in popularity and the idea of decentralized and encrypted currencies catch on, the first alternative cryptocurrencies appear. These are sometimes known as altcoin and generally try to improve on the original Bitcoin design by offering greater speed, anonymity or some other advantage. Among the first to emerge were Namecoin and Litecoin. Currently, there are over 1,000 cryptocurrencies in circulation with new ones frequently appearing.
   2013 – Bitcoin price crashes.
   Shortly after the price of one Bitcoin reaches $1,000 for the first time, the price quickly begins to decline. Many who invested money at this point will have suffered losses as the price plummeted to around $300 – it would be more than two years before it reached $1,000 again.
   2014 – Scams and theft
   Perhaps unsurprisingly for a currency designed with anonymity and lack of control in mind, Bitcoin has proven to be an attractive and lucrative target for criminals. In January 2014, the world’s largest Bitcoin exchange Mt.Gox went offline, and the owners of 850,000Bitcoins never saw them again. Investigations are still trying to get to the bottom of exactly what happened but whatever the story, someone dishonestly got their hands on a haul which at the time was valued at $450 million dollars. At today’s prices, those missing coins would be worth $4.4 billion.
   2016 – Ethereum and ICOs.
   One cryptocurrency came close to stealing Bitcoin’s thunder this year, as enthusiasm grew around the Ethereum platform. This platform uses cryptocurrency known as Ether to facilitate blockchain-based smart contracts and apps. Ethereum’s arrival was marked by the emergence of Initial Coin Offerings (ICOs). These are fundraising platforms that offer investors the chance to trade what are often essentially stocks or shares in startup ventures, in the same manner, that they can invest and trade cryptocurrencies. In the US the SEC warned investors that due to the lack of oversight ICOs could easily be scams or Ponzi schemes disguised as legitimate investments. The Chinese government went one further, by banning them outright.
   2017 –Bitcoin reaches $10,000 and continues to grow
   A gradual increase in the places where Bitcoin could be spent contributed to its continued growth in popularity, during a period where it’s value remained below previous peaks. Gradually as more and more uses emerged, it became clear that more money was flowing into the Bitcoin and cryptocurrency ecosystem. During this period the market cap of all crypto coins rose from $11bn to its current height of over $300bn. Banks including Barclays, Citi Bank, Deutsche Bank, and BNP Paribas have said they are investigating ways they might be able to work with Bitcoin. Meanwhile the technology behind Bitcoin – blockchain – has sparked a revolution in the fintech industry (and beyond) which is only just getting started.

EXPERIENCES:
When I got to know about Bitcoin through a friend in 2014, I was persuaded to invest with a Ponzi Company which was one of the world’s largest Bitcoin exchanges as of 2014 Mt.Gox. In January 2014, the world’s largest Bitcoin exchange Mt.Gox went offline, and the owners of 850,000Bitcoins never saw them again. Investigations are still trying to get to the bottom of exactly what happened but whatever the story, someone dishonestly got their hands on a haul which at the time was valued at $450 million dollars. At today’s prices, those missing coins would be worth $4.4 billion.
I was Convinced because I was a Novice to the platform but I didn’t invest because I was waiting for my friend to cash out and Lo and behold, it all became cock and bull story because the so-called Mt.Gox Exchange Company Packed and went Offline.
Right now they’re Nowhere to be found.
In my presence;
I’ve seen people Invest and make profits out of Crypto and I’ve seen People Invest their lifetime hard-earned money yet they weep.
CONCLUSION:
A cryptocurrency (or cryptocurrency) is a digital asset designed to work as a medium of exchange that uses strong cryptography to secure financial transactions, control the creation of additional units, and verify the transfer of assets.
Cryptocurrencies use decentralized control as opposed to centralized digital currency and central banking systems.
The decentralized control of each cryptocurrency works through distributed ledger technology, typically a blockchain, that serves as a public financial transaction database.
The truth remains that CryptoCurrency is the Future of fast, easy and reliable sources of Online payment systems.
Although Obstacles may arise, users of any cryptocurrency should always look forward to overcoming the cryptocurrency obstacles.
Obstacle overcoming might be in the form of Engaging in Crypto Forums that will enlighten users on updates arising in the Crypto Industry.
