Although you may have heard of Bitcoin, cryptocurrencies are so much more than that. With the help of our guidelines, learning about cryptocurrencies is simple. You can purchase, sell, and store your cryptocurrency in the same amount of time it takes to open a new bank account.

Start with our A-Z of cryptocurrencies to learn more, or jump to our exchanges guide to buy and sell your preferred cryptocurrencies. Don’t forget to read our guide to wallets for more information on how to safeguard your cryptocurrency.

Not only are cryptocurrencies cutting-edge technology. They are currently in use and doing tasks that were unthinkable only a few short years ago.

Consider transferring US dollars in exchange for Indian rupees and having the funds instantly translated to the desired account. Imagine doing it at rates that are competitive, virtually quickly, anonymously, and for a charge of no more than a few hundred rupees.

That is a real-world example. You could accomplish that right now if you so desired, and it is only the tip of the iceberg.

The majority of cryptocurrencies are designed to serve a certain function and do it better than anything else has ever been able to. They are hence ideal for upending established sectors.

What do I need in order to get going?

It’s simpler than it seems to enter the world of cryptocurrency. There are only three easy steps.

Pick a cryptocurrency.

The only two examples are Bitcoin and Ethereum. There are more than a thousand distinct cryptocurrencies in use today, and each one is unique. Many people begin with Bitcoin or Ethereum and then spread it out into a more broad portfolio for added security in the event that a coin’s value drops.

Obtain a wallet

Where do you keep your cryptocurrency? Obviously, in a crypto-wallet.

Although hardware wallets are advised for long-term storage, the majority of these wallets come in the form of computer programmes that you can rapidly download to your phone or PC.

However, not every wallet can accommodate every coin. Before purchasing, confirm that your wallet can accommodate the cryptocurrency of your choice or that you can leave the coin in storage on the exchange where you made the purchase.

On each of our coin pages, we provide a list of suitable wallets for that particular currency. Or read on to discover more about picking the best option for your requirements.

Purchase from a trade

The purchase of your cryptocurrency is the third stage. Typically, the first purchase will include converting fiat money (such USD, EUR, or INR) to your preferred cryptocurrency.

After that, exchanging cryptocurrency amongst each other might be simpler.

First-time purchases typically involve:

What is cryptocurrency, exactly?

Similar to how a physical token like a $100 bill is a physical token with a value of $100, cryptocurrencies are digital tokens with a value.

The fact that digital currencies are entirely electronic is their main drawback. The same thing may happen to a coin, just like how a photograph on the Internet can be repeatedly duplicated until the original is worthless.

A coin must be distinct and impossible to duplicate in order for it to have value in a cryptocurrency.

The development of blockchain technology allowed for this.

The blockchain: what is it?

A blockchain is merely a ledger that records a particular cryptocurrency’s complete history. It is hard to produce any counterfeit money due to the extensive tracking of a currency’s movements and history.

The majority of blockchains are open source and decentralized to avoid tampering.

Open source – The code is made available to the public so that anyone may view how it is implemented. This stops internal manipulation.

Decentralized – Different individuals from all around the world run blockchains. Anyone can start running a “node” on the blockchain at any time with public blockchains like Bitcoin. This prohibits anyone from controlling the network and outside interference.

The name blockchain refers to the precise method it assembles data in the ledger.

A Block in Blockchain

Each block functions as a sort of transactional container. The wallet addresses of the sender and receiver as well as the amount sent are typically included in data collections called transactions on the blockchain.

This data is contained in a block that is created when you complete a transaction. Once a transaction has been included in a block, it cannot be changed or removed. This guarantees the blockchain’s security and dependability.

A block is added to the blockchain once it is ready to be used. It’s similar like sending a parcel.

The chain

Each block is linked together digitally like links in a chain. It is linked to both the transaction that came before it and the transaction that came after it, forming a complete and unbroken record of all transactions made in the cryptocurrency’s history. Anyone may look back and view the transactions that were executed on each block because each block is assigned a number.

In the history of Bitcoin, there have been about 500,000 blocks as of December 2017. Here, you may view the most recent blocks, along with the quantity of Bitcoin they contained.

Most blockchains consist of a single, continuous chain. Others are more complex and may attempt to construct blocks in a web-like structure rather than a single chain by running additional chains off the side of the primary blockchain.

Not all cryptocurrencies even use a blockchain, and not all blockchains function precisely the same. The fundamental ideas and their ramifications are constant.

Cryptocurrencies Mining

Operating the blockchain, confirming the transactions, and adding new blocks to the chain all require computational resources. Mining is the common term for this.

To organise transactions into blocks, connect blocks to the blockchain, and protect the network from outside interference, miners use computational power.

Mining systems for various cryptocurrencies might vary greatly. The two most well-liked are as follows:

  • Evidence of labour. To establish the kind of the future block, a cryptographic puzzle must be solved by miners. If the response is accurate, they will have discovered the relevant block and can securely join it to the chain. Although it is a rather straightforward and secure mining mechanism, it is also incredibly ineffective. Since miners are vying with one another to solve the problems, a lot of energy and computer power is frequently expended. Bitcoin employs a system similar to this.
  • Evidence of stake. This kind of mining entails requesting specific web wallets for holding money from currency owners. After that, the currencies in their wallets will automatically connect to the network and start mining fresh blocks. This is a method of mining coins that is not too inefficient. The main drawbacks are that it is rather difficult and might lead to strange coin hoarding. Proof of stake will replace proof of work in Ethereum.

Cryptocurrencies nearly always provide miners with some sort of incentive to contribute their processing power to the blockchain. This reward is frequently fresh coins of the same sort as the ones they just mined, or it may be the transaction fees paid by all the users whose transactions were included in the newly produced block.

While some currencies will employ proof of stake or proof of labour, others may alternate between the two or employ tweaks of each.

The mining system should be considered when researching a coin. This is due to the potential for direct impact on coin pricing. For instance, increased inflation and a decline in coin value may result from higher mining payouts. Or, as everyone begins purchasing coins to mine with after the switch, word of an impending transition to proof of stake may cause prices to increase.

Prominent alternative cryptocurrencies

Many cryptocurrencies merely attempt to imitate Bitcoin’s popularity, while many others forge their own paths and produce entirely original coins. Historically, all cryptocurrencies other than Bitcoin were referred to as “altcoins,” however today there are numerous different cryptocurrencies.

Just a few of the most well-known cryptocurrencies are listed below to give you an idea of what’s available.

  • Ethereum or Ether (ETH). By offering “smart contracts,” Ethereum was built expressly to take advantage of the possibilities of blockchain technology. These enable 100% reliable and impenetrable automation of computer tasks without the need for a third party.

  • Ripple (XRP). A privately held firm created Ripple specifically to make international money transfers easier. The XRP cryptocurrency makes it possible for money to be moved around the world very quickly and cheaply. Despite being one of the oldest cryptocurrencies still in use, its future has been called into question by a number of legal concerns and a failure to catch on with institutions so far.

  • Dogecoin (DOGE). This coin was designed as a prank and was based on a meme. It was seldom taken seriously and was largely used to tip individuals online. Even so, it increased in value and had a market capitalization of more than $1 billion.

  • Monero (XMR). Monero was created as a cryptocurrency that allows anyone to send and receive entirely anonymous and untraceable payments whenever they need to.

Where can I spend digital currency?

There are several methods for utilising cryptocurrency.

  • According to their intended use

You can always utilise a cryptocurrency exactly as intended, if nothing else. This might be as simple as keeping Bitcoin in your possession or utilising it to purchase other cryptocurrencies.

This might be the Ethereum platform’s smart contract functionality, which uses small amounts of Ether as a kind of transaction fee.

This could be nearly anything for the 1,000+ other coins that are currently in use.

  • Invest in goods or services.

Are you using cash, a credit card, or a cryptocurrency to pay?

Nowadays, many businesses will take popular cryptocurrencies as payment, especially if you use a currency like Bitcoin.

These businesses could be as huge as Microsoft or as little as someone selling used furniture at a neighborhood shop. You can frequently find QR codes that have been printed and pinned next to the cash registers in physical establishments that accept cryptocurrency. To process cryptocurrency payments, these are scanned.

  • Transferring money and tipping with cryptocurrencies

Because cryptocurrency transfers can frequently be completed instantly, some coins, like Dogecoin, have even created their own tipping services. Users tip one another with cash at the touch of a button for amusing or educational posts on Reddit, Twitter, and other social media.

That might not seem like a huge thing, but blockchain technology makes it possible for the first time in history for anyone to pay small amounts—as little as $5 or $10—to someone on the other side of the globe. International transaction costs used to consume these types of transfers.

What to be wary of

You must exercise caution when dealing with your digital currency because cryptocurrencies are not without their risks.


Research cryptocurrencies before investing. There are always two sides to every story, and no single guide will ever be able to tell you everything you need to know about all cryptocurrencies. You also need to be familiar with how wallets and exchanges operate.

Make sure you are well informed before choosing. Before making larger purchases, read instructions, discover reviews, and test drive with tiny, discretionary sums of money.

Be careful.

When using bitcoins, there is no safety net. It’s currently mainly unregulated, and if your bitcoin is stolen, you usually won’t be able to get your money back.

The freedom to use resources other than banks and government funding carries a great deal of responsibility. Here are some pointers:

  • Always double verify the destination address and make sure you’ve entered it correctly before sending cryptocurrency to someone or transferring to your own wallet.
  • Never, ever give anyone your private key or seed phrase (the code for recovering your wallet) or enter it into any website or programme other than your wallet when configuring or recovering it. Other than a personal wallet, there aren’t any other individuals or applications that might possibly ask you for your private key or seed phrase.
  • Always keep your computer’s installation of your wallet secure and free of malware and viruses.
  • Never forget the password to your wallet. Your entire collection of cryptocurrency will be lost and you might not be able to get it back.

Unexpected value

Shocking drops in value are a common problem for bitcoin and cryptocurrencies in general. Always be mindful that the value of your holdings can decrease when buying cryptocurrencies.

Of again, if things turn out differently, this could be to your advantage. Always remember that the bitcoin market is quite unpredictable and that past results do not guarantee future results.

lexicon of cryptocurrencies

Cryptocurrency. digital money that uses encryption techniques to control how it is used and how it is created. Cryptocurrency is ungoverned and uncontrolled by any authority, in contrast to fiat money like US dollars, euros, yen, and rupees.

Bitcoin. is a virtual currency that uses peer-to-peer technology to make payments almost instantly. Under the alias Satoshi Nakamoto, an unnamed programmer or group of programmers created Bitcoin.

Bitcoin Address. A string of alphanumeric characters used to receive Bitcoin is also known as a key. Private addresses, or addresses that aren’t available to all users, often start with a 5 or 6, as opposed to public addresses, which typically start with a 1 or 3.

Bitcoin exchange– a website or online marketplace where people can purchase and sell bitcoin for different currencies.

blockchain– a public digital ledger where a cryptocurrency’s full history is chronologically documented.

block prize. the quantity of cryptocurrency created when a hash has been solved by a “miner.”

electronic wallet An electronic device, often known as a “e-wallet,” that securely saves passwords, credit card information, and other personal data enables customers to make digital payments online or at merchant locations that accept them.

hash. a mathematical conundrum that must be resolved by a cryptocurrency “miner” in order to include the next block on a blockchain.

mining. a procedure used to introduce a cryptocurrency into circulation. A block of cash is awarded to “miners” who successfully solve a computational problem along the public blockchain.

node. A computer connected to the Bitcoin network.

proof of work. A hash — or computational puzzle to unlock a cryptocurrency — that is so difficult, it could only have been solved through significant work or power.

proof of stake. A system that replaces the concept of “mining” a cryptocurrency with a consensus algorithm, whereby miners put up a stake of their currency to verify a block of transactions.

An overview of cryptocurrency history

In the 1980s, the path toward cryptocurrencies was paved. Banks started looking into and promoting the idea of points of sale, where a customer can use a credit card instead of cash to pay for goods, in an effort to preserve the cash of small stores and gas stations.

Later, in the 1990s, emerged PayPal, a web-based payment method that is still in use today. In addition to introducing the concept of transferring fiat currency directly between end users totally online, this provided retailers the ability to accept credit card payments online. Following PayPal’s demonstration that the internet can be a reliable means of moving money, similar services like WebMoney, a Russian competitor to PayPal, and e-Gold, an American company that allowed customers to purchase gold online and have it held for them, were developed.

After the FBI took down e-Gold in the 2000s, cryptocurrencies started to appear on mailing lists and in the cryptography community. People like Jacob Appelbaum, the creator of Tor, and Julian Assange, the man behind WikiLeaks, belonged to a group called the Cypherpunks.

Unfortunately, until Satoshi Nakamoto published a paper titled “Bitcoin: A Peer-to-Peer Electronic Cash System” in 2008, none of these cryptocurrencies could amass the required momentum to propel them into the public’s attention.

In the years that followed, Bitcoin expanded to become not only the most popular cryptocurrency on the market but also a household name, even among non-cryptocurrency enthusiasts.

Eventually, Bitcoin gave birth to hundreds of cryptocurrencies that are together referred to as altcoins. Some of these altcoins are little more than Bitcoin duplicates, while others are attempting to use the underlying blockchain technology to disrupt not only the financial industry but also how we think about apps and internet services in an effort to address the centralization issue we face today.

The issue with centralized government

If you read any writing about Bitcoin and cryptocurrencies, you will eventually run into the idea of decentralization. You must first comprehend centralization in order to comprehend decentralization.

If we look closely at the society we live in today, a world filled with information and data about who we are, what we do, and what we like, we see that just a few sizable institutions—private and public organizations, as well as the government—hold our information. On servers that are located in a central place, the dataset that represents you is stored, including your financial information, emails, Facebook messages, and likes. For instance, your bank’s servers house all of your financial information, including your account balance, past transactions, and loans. Although your bank may have several servers for backup and audit purposes, everything is still essentially located there: in your bank.

Let’s assume that a cracker—a hostile hacker—attacks the servers of your bank and tampers with your account, making your balance zero. How will you demonstrate that you didn’t simply take your entire bank account? How will your bank be able to validate your hacking claim?

The Cypherpunks, the group that gave rise to cryptocurrencies, were aware of this dire situation and worked to improve it. Because each cryptocurrency user maintains a copy of every user’s transaction history, cryptocurrencies are referred to as decentralized systems. You obtain the complete history of a coin, including every transaction ever performed, the moment you join a blockchain. If a user objects to a transaction (for example, if a cracker changes the value of their wallet from 1 BTC to 1,000 BTC), at least 51% of the cryptocurrency’s users must agree. That 51% then decides the proper amount.

The beauty of cryptocurrency and decentralization is this automatic consensus. Crackers are unable to assault a single server. Because each user maintains a copy of the blockchain, they would need to persuade 51% of all users.
