The Cryptocurrency Boom: Understanding Digital Assets and Their Future
In the past few years, thousands of new cryptocurrencies have emerged, each promising something unique. Bitcoin was the first, and its value soared to nearly $20,000 in late 2017 before crashing by over 60% in early 2018. It took Bitcoin three years to recover, but by the end of 2020, it doubled in value within a month. Now, in 2021, major corporations are investing, and even Wall Street skeptics are changing their stance.
Cryptocurrency has become impossible to ignore.
But let’s take a step back. What exactly are cryptocurrencies, how do they work, and why is there so much excitement surrounding them? You’re in the right place to find out.
What is Cryptocurrency?
Cryptocurrency is a digital-only token that relies on cryptography to regulate how tokens are created, traded, and kept secure. One of the most appealing aspects is that cryptocurrencies are decentralized—meaning they don’t need a central bank or government to control them.
Bitcoin, the first cryptocurrency, was created by an anonymous person (or group) using the pseudonym Satoshi Nakamoto. It was introduced in a 2008 whitepaper titled “A peer-to-peer electronic cash system.” The Bitcoin blockchain, which underpins Bitcoin transactions, went live in January 2009. Today, there are many other blockchains, each supporting different cryptocurrencies.
In short, cryptocurrencies are:
- Digital: Cryptocurrencies exist purely online and have no physical form.
- Decentralized: Their transactions are stored in multiple locations (nodes) across a global network.
- Peer-to-peer: They allow direct transfers between users without a middleman like a bank.
How Are Cryptocurrencies Created?
Most cryptocurrencies are created through a process called mining. Miners use powerful computers to solve complex cryptographic puzzles that verify transaction records, which are grouped into “blocks” on the blockchain. For their efforts, miners are rewarded with new coins, adding to the total supply. For instance, on the Bitcoin blockchain, the reward for mining is halved every four years to slow down Bitcoin’s creation.
How Are Cryptocurrencies Used?
While cryptocurrencies like Bitcoin were originally designed to be an alternative to traditional money, their use cases have grown. Today, they are used for more than just monetary transactions:
- Litecoin: Created in 2011, Litecoin is a fork (altered version) of Bitcoin, intended to be the “silver” to Bitcoin’s “gold.”
- Ethereum: Launched in 2015, Ethereum is designed to support decentralized applications (Dapps) and smart contracts. Its token is called Ether (ETH).
- Filecoin: Launched in 2020, Filecoin allows people to rent out storage space on their computers, functioning like a decentralized Dropbox. Its token is FIL.
Bitcoin might have started the cryptocurrency revolution, but many others have followed, each addressing different needs and challenges.
The Three Generations of Cryptocurrencies
Bitcoin solved the challenge of creating digital money, but it had limitations. Since its inception, developers have been busy creating newer cryptocurrencies that address various problems and offer enhanced features. This has led to the rapid evolution of the crypto space.
Why Do People Prefer Cryptocurrencies Over Government-Issued Currencies?
- Semi-anonymity: Cryptocurrencies can be designed to protect the identity of users, though all transactions associated with a wallet address are publicly viewable.
- Independence from governments: People in countries with unstable currencies use cryptocurrencies as an alternative way to buy goods and services.
- Borderless transactions: Like the internet, cryptocurrencies can be sent anywhere in the world.
- Security: Decentralized ledgers are difficult to hack since no single party controls them.
- Lower fees and faster transactions: Crypto transactions often cost less and are processed more quickly than international money transfers in traditional finance.
- Smart contracts: Cryptocurrencies can also store and execute contracts automatically between parties.
The Future of Cryptocurrencies
We are still at the beginning of the cryptocurrency era. Many new coins will emerge, while others may disappear. Some will become incredibly valuable, while others may lose their value entirely.
But one thing is certain: the technology behind cryptocurrencies, and the industry that has developed around them, is here to stay. The world of digital assets will continue to evolve and shape the future of finance.
