The Digital Gold Rush - Understanding Cryptocurrency and Blockchain.

A little over ten years ago, the word cryptocurrency was virtually unknown outside of certain internet forums. Now it has invaded the consciousness of average investors and speculators on Wall Street. Cryptocurrency has done what was thought to be impossible, it has fundamentally changed our worldview. The implications of this technology can be likened to the invention of the printing press, or the telephone. To truly understand what cryptocurrency is, we need to understand what makes it tick.

Crypto
currency - The Basics.

At the most basic level, cryptocurrency is simply digital cash. The "crypto" refers to the cryptography or complex mathematical algorithms used to secure the network and the transactions taking place on it. Unlike the US dollar, the Euro, or Yen, cryptocurrency is decentralized, meaning that it is not controlled by a government or issuing authority. Instead of trusting the central bank to print an appropriate amount of money to stimulate the economy, people trust the mathematics of the system to keep everything honest.

One of the key features of cryptocurrency is that it is a "decentralized consensus mechanism." This means that the validity of transactions taking place on the system are not governed or regulated by one central entity, but instead are agreed upon by all members of the network.

To better understand where cryptocurrency comes from, we need to understand what happens after the coins are created.

Blockchain - The Technology Behind the Tokens

Blockchain is the underlying technology that enables large-scale financial transactions on the internet and with confidence, without requiring a trusted third party.

Think of it as a decentralized digital ledger (record of information) that cannot be hacked or tampered with.

Say Alice wants to send Bitcoins (BTC) to Bob. Her payment request will first have to be gathered together with all the other payments that have occurred in the meantime in order to update the transaction record.

This process takes place via thousands of computers around the globe. Moreover, once added to the blockchain, data cannot be deleted or altered. The only way to delete or change this information is to edit it on every computer that has access to the blockchain. This makes the process transparent and almost impossible to hack.

Now that we have discussed the key components of cryptocurrencies, let us proceed to the next section, which will familiarize us with different types of digital currencies.

Bitcoin, Ether, Stablecoins, and Altcoins

Now you may be wondering what are the different types of cryptocurrencies. Well there are many but the most common fall under 3 categories, Bitcoin (BTC), Altcoins, and Stablecoins.

Bitcoin - Is the OG cryptocurrency (first released in 2009) and by far the largest by market cap. Bitcoin is decentralized, borderless, permissionless, and most importantly has value. When Satoshi Nakamoto (the creator of Bitcoin) launched Bitcoin he wrote in the white paper that stated its purpose was to be "a peer-to-peer electronic cash system." . Bitcoin was supposed to be the "PayPal of the internet" a medium for exchange between people for goods and services. However, Bitcoin became something he didn't anticipate; it became what some call "digital gold" a store of value that people use to protect themselves from inflation.

Ethereum - Is a cryptocurrency similar to Bitcoin but was launched in 2015 by Vitalik Buterin, who also had a vision for its use. Ethereum had the same cornerstones of being decentralized, borderless, permissionless, but had one major differentiator from Bitcoin, Smart Contracts. Smart Contracts are self-executing contracts with the terms of agreement written directly into lines of code. With Ethereum, you can create decentralized applications (Dapps) on its blockchain, issue tokens (ERC-20), and NFTs (Non Fungible Tokens).

Altcoins - Are alternative coins to Bitcoin, hence the name. Some Altcoins like Solana (SOL) want to compete with Ethereum and offer more efficient transactions than both Bitcoin and Ethereum. Some Stablecoins like Tether (USDT) and USD Coin (USDC) want to be digital cash. They are backed 1:1 with the US Dollar.

Cryptocurrency may have some risks, but it also has some major benefits and advantages over the current financial system.

The Advantages of Cryptocurrency Explained

Cryptocurrency proponents correctly argue that the technology has a number of advantages over the traditional financial system.

Financial Inclusion - Nearly 1.4 billion people globally don't have access to a bank account but do have access to a smartphone. Cryptocurrency enables financial freedom to people that previously didn't have any.

Lower Fees and Higher Speeds - Traditional cross-border wire transfers can take anywhere from 3-7 days to clear and have prohibitively high fees. With crypto, transactions can take place in seconds with fees as low as a few cents.

True Ownership - At the end of the day, when you deposit money into a bank, you aren't actually "owning" anything. If a bank's digital servers were to get hacked, you wouldn't be able to access your money. With cryptocurrency, you have full ownership of your assets which are secured by cryptography. No one, not even banks or governments can take them from you.

Despite these benefits, there are some glaring disadvantages that must be considered as well.

The Disadvantages of Cryptocurrency

Cryptocurrency is a fascinating innovation, but it is by no means perfect. Here are some of the key disadvantages of using crypto:

Price Volatility - Cryptocurrencies are known to be extremely volatile. This is because they are not tied to anything of value. Their worth is purely based on what the market is willing to pay for them. It's not uncommon for prices to swing by 20% or more within a single trading week.

Regulatory Environment - The regulatory environment around cryptocurrency is very murky right now. Some governments are considering banning them entirely while others want to impose strict regulations on crypto exchanges and trading. This uncertainty can often impact crypto prices tremendously.

Security Risks - While blockchain technology itself is virtually unhackable, crypto exchanges and associated applications are often prone to exploits and various security threats. In addition, there are also scams and frauds that take place in the space that investors need to be wary of. Unlike traditional banks which have customer support and can assist you in recovering lost funds, crypto companies cannot do that. If you make a mistake and lose your crypto to a hacker, that's it.

As society moves toward a cashless future, cryptocurrency seems poised to play a growing role in our day-to-day financial transactions.

FAQs

1. Is cryptocurrency legal?

A short answer is yes, it is legal. Well, mostly. Some countries have indeed banned any crypto transactions. It is best to do some research as to whether or not it is legal where you are.

2. How do people make money with cryptocurrency?

The most common way for people to benefit from the cryptocurrency is to speculate on its value. This can be done by buying crypto assets in the hopes that their value will increase so that it can later be sold for a higher price than it was bought. The other way of profiting from crypto is by mining or staking the coins.

3. What happens if I lose my crypto wallet?

There is no way to recover lost crypto funds. This is because there is no entity that governs or controls crypto assets like there is with traditional banks. If you lose your wallet keys, or your wallet "seeds", your money is gone for good.

4. Can a cryptocurrency be hacked?

Major blockchains like Bitcoin and Ethereum cannot be hacked. However crypto exchanges and apps which are built on top of them can be compromised and hacked. This is another reason why you should think carefully before investing in crypto assets.

5. What makes a cryptocurrency valuable?

The easiest way to understand the value of crypto is to compare it to what we know as fiat money. So, the value of cryptocurrencies such as Bitcoin and Ethereum is derived from their supply-demand and their utility. Like how the dollar has value because the government says so even though it is not backed by anything, crypto is the same. Only here the value is given by the people who are willing to pay for it.
