What cryptocurrency is and how it works ?

Cryptocurrency, also referred to as crypto-currency or crypto, is any virtual or digital money that employs encryption to safeguard transactions. Cryptocurrencies use a decentralized mechanism to record transactions and issue new units instead of a central body issuing or controlling them.

‍

What is a digital currency?

A digital payment method called cryptocurrency doesn't rely on banks to validate transactions. Peer-to-peer technology makes it possible for anybody, anywhere, to give and receive money. Digital entries to an online database detailing individual transactions are the only thing that cryptocurrency payments are made with, as opposed to actual money that is carried and exchanged in the real world. A public ledger keeps track of all cryptocurrency transactions that take place when money is transferred. Crypto wallets are used to store cryptocurrency.

‍

The fact that cryptocurrency uses encryption to confirm transactions is how it got its name. This indicates that the storage and transmission of bitcoin data between wallets and to public ledgers require sophisticated coding. Encryption is used to make things safe and secure.

‍

Bitcoin was the first cryptocurrency and is still the most well-known today. It was launched in 2009. The main attraction of cryptocurrencies is trading for financial gain, with speculators occasionally sending prices through the roof.

‍

What is the working mechanism of cryptocurrency?

Blockchain, a distributed public ledger that records all transactions and is updated by currency holders, is the foundation upon which cryptocurrencies operate.

‍

Through a procedure known as mining, which uses computer power to solve challenging mathematical problems that yield coins, units of cryptocurrency are created. Cryptographic wallets can be used by users to store and spend the currencies they purchase from brokers.

‍

You don't possess anything material if you own cryptocurrency. What you possess is a key that lets you transfer data or a unit of measurement from one person to another without the assistance of a reliable outsider.

‍

Despite the fact that Bitcoin has been available since 2009, there are still many untapped financial applications for cryptocurrencies and blockchain technology, with more expected in the future. Technology may someday be used to trade financial assets such as stocks, bonds, and other securities.

‍

Examples of cryptocurrencies

Numerous cryptocurrency exist in the thousands. Among the most well-known are

‍

Bitcoin:

‍

Bitcoin was the first cryptocurrency and is now the most traded, having beenfounded in 2009. The creator of the currency, Satoshi Nakamoto, is generally accepted to have used a pseudonym to refer to a person or group of persons whose true identity is still unknown.

‍

Ethereum

‍

Ethereum is a blockchain platform that was created in 2015 and has its own cryptocurrency known as Ether (ETH) or Ethereum. After Bitcoin, it is the most widely used cryptocurrency.

‍

Litecoin:

‍

The most striking similarity between this money and bitcoin is how quickly new developments have been developed, such as quicker payment processing and expanded transaction limits.

‍

Ripple:

‍

Founded in 2012, Ripple is a distributed ledger technology. Not just cryptocurrency transactions but also other types of transactions can be tracked using ripple. Its creator business has collaborated with a number of banks and financial organizations.

‍

To differentiate them from the original, cryptocurrencies that are not based on Bitcoin are referred to as "altcoins" as a group.

How to buy cryptocurrency

You may be wondering how to buy cryptocurrency safely. There are typically three steps involved. These are:
‍

Step 1: Choosing a platform

The first step is deciding which platform to use. Generally, you can choose between a traditional broker or dedicated cryptocurrency exchange:
‍

• Traditional brokers. These are online brokers who offer ways to buy and sell cryptocurrency, as well as other financial assets like stocks, bonds, and ETFs. These platforms tend to offer lower trading costs but fewer crypto features.
  ‍
• Cryptocurrency exchanges. There are many cryptocurrency exchanges to choose from, each offering different cryptocurrencies, wallet storage, interest-bearing account options, and more. Many exchanges charge asset-based fees.

When comparing different platforms, consider which cryptocurrencies are on offer, what fees they charge, their security features, storage and withdrawal options, and any educational resources.

‍

Step2: Add money to your account

‍

The next step is to fund your account so you can start trading after selecting your platform. Although this varies by platform, the majority of cryptocurrency exchanges let users buy cryptocurrency with fiat (i.e., government-issued) currencies like the US Dollar, the British Pound, or the Euro using their debit or credit cards.

‍

Credit card purchases of cryptocurrency are regarded as dangerous, and some exchanges do not allow them. Additionally, some credit card providers prohibit cryptocurrency transactions. This is due to the extreme volatility of cryptocurrencies, and it is not wise to take a chance on incurring debt for some assets or even paying hefty credit card transaction fees.

‍

Additionally, wire transfers and ACH transactions are accepted on certain platforms. Each platform has different acceptable payment methods and processing times for deposits and withdrawals. The time it takes for deposits to settle also differs depending on the mode of payment.

‍

Fees are a crucial consideration. These consist of trading costs in addition to possible transaction fees for deposits and withdrawals. Fees will differ depending on the platform and payment method, so you should do some preliminary study on this.

‍

Step 3: Placing a order

‍

You can use the web or mobile platform of your broker or exchange to make an order. If you want to acquire cryptocurrency, you can do so by clicking "buy," choose the type of order, entering the quantity you wish to buy, and finalizing the transaction. "Sell" orders follow the same procedure.

‍

There are also other ways to invest in crypto. These include payment services like PayPal, Cash App, and Venmo, which allow users to buy, sell, or hold cryptocurrencies. In addition, there are the following investment vehicles:

• Bitcoin trusts: You can buy shares of Bitcoin trusts with a regular brokerage account. These vehicles give retail investors exposure to crypto through the stock market. 
  ‍
• Bitcoin mutual funds: There are Bitcoin ETFs and Bitcoin mutual funds to choose from. 
  ‍
• Blockchain stocks or ETFs: You can also indirectly invest in crypto through blockchain companies that specialize in the technology behind crypto and crypto transactions. Alternatively, you can buy stocks or ETFs of companies that use blockchain

How to store cryptocurrency

Once you have purchased cryptocurrency, you need to store it safely to protect it from hacks or theft. Usually, cryptocurrency is stored in crypto wallets, which are physical devices or online software used to store the private keys to your cryptocurrencies securely. Some exchanges provide wallet services, making it easy for you to store directly through the platform. However, not all exchanges or brokers automatically provide wallet services for you.

There are different wallet providers to choose from. The terms “hot wallet” and “cold wallet” are used:
‍

• Hot wallet storage: "hot wallets" refer to crypto storage that uses online software to protect the private keys to your assets.
• Cold wallet storage: Unlike hot wallets, cold wallets (also known as hardware wallets) rely on offline electronic devices to securely store your private keys.

Typically, cold wallets tend to charge fees, while hot wallets don't.

What can you buy with cryptocurrency?

‍

When Bitcoin was initially introduced, its goal was to serve as a medium for regular transactions, enabling people to purchase anything from a computer to a cup of coffee to expensive goods like real estate. Although more institutions are beginning to embrace cryptocurrencies, significant transactions involving them are still uncommon. That hasn't fully happened. Nevertheless, utilizing cryptocurrency, a large range of goods can be purchased via e-commerce platforms. These are a few instances:

‍

Technology and online shopping portals:

‍

Many tech companies, like Microsoft, AT&T, and Newegg.com, accept cryptocurrency on their websites. One of the first online retailers to take Bitcoin was Overstock. It is also accepted by Home Depot, Rakuten, and Shopify.

‍

Luxury Products:

‍

A few upscale stores will take cryptocurrency as payment. For instance, Bitdials, an online luxury shop, accepts Bitcoin in exchange for luxury watches like Patek Philippe, Rolex, and others.

‍

Cars:

Some car dealers – from mass-market brands to high-end luxury dealers – already accept cryptocurrency as payment.
‍

Insurance:

In April 2021, Swiss insurer AXA announced that it had begun accepting Bitcoin as a mode of payment for all its lines of insurance except life insurance (due to regulatory issues). Premier Shield Insurance, which sells home and auto insurance policies in the US, also accepts Bitcoin for premium payments.

If you want to spend cryptocurrency at a retailer that doesn’t accept it directly, you can use a cryptocurrency debit card, such as BitPay in the US.
‍

Are cryptocurrencies secure?

Blockchain technology is typically used in the development of cryptocurrencies. Blockchain explains the process of grouping transactions into "blocks" and assigning a time stamp. Although it's a pretty sophisticated and involved procedure, the end product is a digital record of cryptocurrency transactions that is difficult for hackers to alter.

‍

Furthermore, a two-factor authentication procedure is necessary for transactions. To begin a transaction, for example, you might be prompted to provide your username and password. Next, a code of authentication may need to be entered and texted to your personal cell phone.

‍

Cryptocurrencies can still be hacked even with security measures in place. Numerous expensive attacks have severely harmed cryptocurrency startups. The largest cryptocurrency attacks of 2018 involved the loss of $534 million from Coincheck and $195 million from BitGrail due to hackers.

‍

In contrast to money that is backed by the government, virtual currencies are solely determined by supply and demand. This may lead to erratic fluctuations that bring substantial profits or losses to investors. Furthermore, investments in cryptocurrencies are protected by considerably fewer regulations than those in more conventional financial instruments like stocks, bonds, and mutual funds.
