A cryptocurrency is a digital payment system used to buy goods and services virtually. It does not rely on banks to verify transactions but instead uses an online ledger with solid cryptography to secure them. The digital currency uses a decentralised system to record transactions and offer new units because it does not have a regulatory body or a central issuing. 

Cryptocurrency is used interchangeably with “crypto” and crypto-currency. The principal interest in this digital currency is to trade for profits, with speculators at times taking the prices upward.

The most famous crypto, Bitcoin, had volatile price tendencies hitting about $65,000 in April and crashing nearly half of its value in May. By September, the price had swiftly boomed again, reaching its all-time highs above $66,000 before dropping again. This writing discusses what cryptocurrencies are, how to purchase them and secure yourself. Read on to discover the seven things to know and consider in crypto-currency.

Cryptocurrency is a digital peer-to-peer system that enables individuals to make and receive payments from whichever location. Crypto payments exist entirely as digital entries to an online database with particular transactions rather than substantial money used in the real world.

Cryptocurrency derived its name from encryption, which is used to verify transactions. The objective of encryption is to offer security and safety. Additionally, the currency is stored in digital wallets; thus, advanced coding is needed to store and transmit cryptocurrency data between the wallets and the blockchain.

Companies issued their currencies called tokens, traded mainly for their services or goods and almost similar to casino chips or arcade tokens. Therefore, you will oblige to exchange the real money for a digital currency for you to access the services and goods.

The most profound feature of crypto is that no government or central authority controls it.

Crypto users acquire cryptocurrency units through a process called mining that uses computer power to solve complicated algorithms to generate coins. Also, the digital currency is purchased from crypto-currency exchanges or brokers, and it is then stored in digital wallets. Cryptocurrency is not a tangible asset; however, it is a key that allows you to move records or units of measure from one individual to another without involving a third intermediary.

3. Why are cryptocurrencies so popular?

Digital currencies attract supporters for various reasons that differ from one individual to another. The most known factors are:

Some users like the crypto technology, blockchain, a decentralised recording and processing system that is more secure than traditional payments systems.

Banks tend to decrease the value of money through inflation over time; thus, some supporters like the fact that the digital currency gets rid of central banks from controlling the money supply. 

Some speculators like cryptocurrency because it is growing up in value and have no appeal in its long-term acceptance as a means to move funds.

The Crypto community sees cryptocurrencies such as Bitcoin as the future currency; hence they are racing to buy it before it shoots in value.

What can you buy with cryptocurrency?

When Bitcoin was launched in 2009, its primary purpose was to act as a medium of daily transactions, making it possible to buy a cup of tea or a laptop or even make more significant purchases such as real estate investments. However, the first primary purpose has not materialised since the number of institutions accepting digital currencies continues to grow. Nevertheless, it is possible to purchase various products and services from e-commerce websites using crypto. 

Here are some examples:

Cars – Many car dealers, from mass-market brands to high-end luxury dealers, already accept digital currency as a form of payment.

Luxury goods – Some luxury retailers allow cryptocurrency as a payment method for their products and services. For instance, online luxury retailer Bitdials offers Rolex and other luxurious watches in exchange for Bitcoin.

Insurance – some insurers accept Bitcoin as the mode of payment; for example, in April 2021, Swiss insurer AXA announced that it would be using Bitcoin to pay all its insurance lines except life insurance due to regulatory issues. Also, Premier Shield Insurance accepts Bitcoin for premium payments. The company is based in the United States, and it sells home and auto insurance policies.

Technology and e-commerce sites – several companies that trade tech products accept digital currencies as a payment method on their websites, such as Microsoft, Shopify and Home Depot. However, an e-commerce platform called Overstock was among the first to accept Bitcoin as a payment method.

You can use a crypto debit card such as BitPay to spend your digital currency at a retailer that does not accept it directly in the United States.

4. Is cryptocurrency a good investment?

It is possible to get filthy rich by trading cryptocurrencies in 2021, but you could also lose all of your money in a matter of seconds. Both are possible since investing in digital currency is risky, and however, it can be potentially highly profitable in the same measure.

Cryptocurrencies do not generate cash flow, unlike real money, and despite their value growth, most investors do not see it as a real investment but mere speculation. For an individual to profit in crypto, another person has to pay more for the token than you did. Cryptocurrencies contrast the well-managed businesses, which inflate in value over time by increasing the profitability and cash flow of the venture; thus, likening it to the “greater fool” theory of investment.

Notable individuals in the investor community have advised the wannabe investors to steer off the cryptocurrency business. For instance, a legendary investor Warren Buffet compared Bitcoin to paper checks and questioned the coin’s value. A currency needs stability and consistency for the traders and consumers to determine a fair cost for the services and goods.

Cryptocurrency has recorded a lot of volatility throughout much of its history. Taking an example of Bitcoin, it traded at nearly $20,000 by fall of 2017; a year later, its price crashed to as low as $3200 and in December 2020, it was trading at its highs again.

If cryptocurrencies were worth more in future, the community would be reluctant to spend and circulate them today; thus, they would be less practical as a currency. The price volatility creates a dilemma since it would be unthoughtful to sell a Bitcoin at a lower price, knowing it will be three times worth more in value in the following year.

Cryptocurrency frauds and scams

7. How do I protect myself?

If you want to purchase digital currency in an Initial Coin Offering (ICO), read the fine print in the company’s leaflet for the following information:

The availability of other investors in the company- is a good sign since it means other famous investors want a piece of the token.

Know whether you will own a stake in the company or just tokens or currency. Owning a stake means you will participate in its earnings, while buying tokens means you are entitled to use them, like chips in a casino.

The company owner, an identifiable and well-known owner, is an appositive sign.

The further the development of the currency, the less risky it is. Therefore, It is crucial to know whether the coin is already developed or searching for funds to build it.

If the prospectus is detailed, there is a better chance that the currency is legitimate. However, the legitimacy of the coin does not mean it will succeed. Having cryptocurrencies exposes you to the risk of theft as hackers try to break into digital wallets where people store their virtual currency to steal it. Therefore, it is vital to use two-factor authentication processes when transacting.

Cryptocurrency is any currency that exists virtually or digitally and uses cryptography to protect buying and selling payments. It is a decentralised system that enables transactions from anywhere globally. Cryptocurrencies work by running on a Blockchain where all transactions are recorded, updated, and held by currency holders. Buying digital currency involves choosing a platform, creating an account and eventually placing an order. The coins are stored in a wallet. Also, the legality of virtual currency depends on the country; for example, cryptocurrencies are banned in China but legalised in the United States. Crypto crimes are on the rise, and it is essential to be aware and consider ways to protect yourself. Despite cryptocurrency being risky, it is a good investment if you want to increase direct exposure to the demand for digital currency.
