What is Cryptocurrency? #cryptocurrency #pi

​In my opinion, cryptocurrency is the future of money and financial systems due to its decentralized, secure, and innovative nature. Since a friend, let's call her Lynene, asked me to explain it, and I couldn't do it verbally, I will break it down in a way that covers what cryptocurrency is, how it works, why it's seen as the future, and what it's backed by. Writing is so much easier than talking. 

What is it?
Cryptocurrency is a digital form of money that uses cryptography for security. Unlike traditional currencies issued by governments (fiat money like USD, EUR, etc.), cryptocurrencies operate on decentralized networks based on blockchain technology.

So, what is the block chain? 
 A blockchain is a distributed ledger that records all transactions across a network of computers. It's decentralized and transparent, meaning no single entity controls it, i.e. government institutions and banks and the Fed. Each "block" in the chain contains a record of transactions, and blocks are linked in a chronological sequence, hence the term "blockchain". Cryptocurrency is also safe from manipulation. You cannot simply print more, so inflation and deflation do not exist. You cannot steal it because it is encrypted. The only way it can be lost is if you lose it, by giving away complex passcode secrets. 

Examples of Cryptocurrencies: 

1. Bitcoin (BTC): The first and most well-known cryptocurrency.
2. Ethereum (ETH): Known for smart contracts and decentralized applications (DApps).
3. Ripple (XRP): Primarily used for cross-border payments.
4. Litecoin (LTC): A faster alternative to Bitcoin.
5. Pi (Pi) An innovative platform that allows people from all socioeconomic levels to participate in mining and earning Pi cryptocurrency

How Does Cryptocurrency Work?
Cryptocurrencies rely on blockchain technology and a consensus mechanism to ensure security, integrity, and decentralization.

Unlike banks or central authorities, cryptocurrencies operate on a peer-to-peer network. This means there is no central control, and transactions happen directly between users. When you transfer money through a bank, it has to go through several steps to make it into your bank account sometimes taking several days. With cryptocurrency money is passed from one person to another instantaneously. You own your own digital wallet, and your cryptocurrency is stored inside. It is secured by using amazingly complex words and numbers, face verification and in some cases, thumb print. 

In many cryptocurrencies like Bitcoin, transactions are verified through a process called mining, where miners solve complex mathematical problems to add new blocks to the blockchain. Miners are rewarded with cryptocurrency for their work.

Some cryptocurrencies, like Ethereum (after transitioning to Ethereum 2.0), use a different consensus mechanism called Proof of Stake, where validators (who hold a stake in the network) confirm transactions. This process is energy-efficient compared to Proof of Work.

Some examples: 

1. Public Key: Like an account number at a bank; it's shared with others to receive funds. 
2. Private Key: Like a password; it's used to sign transactions and prove ownership of the funds. Think of it like your signature on a check. In digital currency it is amazingly complex.
3. Smart Contracts: Some cryptocurrencies, like Ethereum, also allow for smart contracts—self-executing contracts with the terms of the agreement directly written into code. This reduces the need for intermediaries.

Why is Cryptocurrency the Future?
There are several reasons why I think cryptocurrency is the future of finance. 

1. No intermediaries: Cryptocurrencies eliminate the need for banks or other intermediaries in financial transactions. This creates faster, cheaper, and more transparent systems. Plus, you don't have to pay any fees. 
2. Global access: People in countries with unstable currencies or limited banking access can use cryptocurrency, which will be transformative. They will not have to rely on banks or governmental institutions that regulate money by, in some cases, force. Since you cannot hold it physically, no one can take it from you. It cannot be confiscated, and it is reliable. 

Security

1. Cryptography: Cryptocurrencies are highly secure due to the use of cryptographic techniques. Blockchain’s structure makes it nearly impossible to alter past transactions without being detected, providing transparency and security.
2. Immutability: Once a transaction is added to the blockchain, it cannot be changed or deleted, which ensures data integrity.

Efficiency and Cost-Effectiveness

1. Low Transaction Fees: Traditional banking systems charge fees for transactions, especially for international transfers. Cryptocurrencies often have lower or no fees, and transactions can happen within minutes (or seconds in some cases like Ripple or Litecoin).
2. 24/7 Availability: Unlike traditional banks, which are limited by working hours, cryptocurrency networks operate 24/7, offering users flexibility.

Potential for Innovation

1. Smart Contracts and DApps: With blockchain platforms like Ethereum, cryptocurrency can go beyond simple transactions to facilitate applications (decentralized apps or DApps) that work without centralized servers or intermediaries.
2. Programmable Money: Cryptocurrencies like Bitcoin and Ethereum are programmable, meaning developers can create new features, products, and services on top of these networks.

Explanation: 

1. Smart contract: An electronic contract that can be executed automatically using blockchain technology. It executes when specific conditions are met.
2. DApp (Decentralized Application): A broader concept than a smart contract. DApps use one or more smart contracts as their backend to operate. They can bundle multiple smart contracts together and provide a friendly interface for users

Store of Value (Digital Gold)

1. Some view cryptocurrencies like Bitcoin as a store of value, akin to digital gold. With a limited supply (Bitcoin has a maximum supply of 21 million coins), it's seen as a hedge against inflation, much like precious metals. Fiat money, specifically the US, was once backed by gold. In 1972, President Richard Nixon removed fiat money from the gold standard. So, in essence, the only value our dollar has is backed by the US government. 

Increasing Adoption
Major companies, financial institutions, and even governments are becoming more open to cryptocurrencies. Examples include:

1. Bitcoin ETFs (exchange-traded funds) that give investors exposure to Bitcoin without owning it directly. This is much like a mutual fund only your fund contains Bitcoin. 
2. Central Bank Digital Currencies (CBDCs): Some governments are exploring or launching their own digital currencies, built on blockchain technology. Why? It is safe, and transactions are secure and immediate. 
3. Institutional Investment: Major financial institutions like Tesla, MicroStrategy, and Square have invested in Bitcoin, helping legitimize it as an asset class.

Other companies that accept Bitcoin:

1. PayPal
2. Wikipedia
3. Microsoft
4. AT&T
5. Apple
6. Starbucks
7. Whole Foods
8. Home Depot
9. Shopify

US States that support cryptocurrency:

1. Wyoming: Exempted crypto businesses from money transmission licenses, introduced a Financial Technology Sandbox, and offers no state income tax.
2. Florida: Exempted crypto businesses from money transmission licenses, launched a pilot program for paying state fees in cryptocurrency, and has no state income tax.
3. Texas: Allowed state-chartered banks to offer cryptocurrency custody, provides benefits for miners, and has no state income tax.
4. New Hampshire: Exempted crypto businesses from money transmission regulations and does not tax income or capital gains (only taxes interest and dividends).
5. Colorado: Launched a program to allow taxpayers to pay state taxes in cryptocurrency; income is taxed at a flat 4.4%.
6. Arizona: Clarified that airdrops are tax-free at the state level; state income is taxed at a flat rate of 2.5%.

3. Australia
4. European Union
5. France
6. Denmark

What is Cryptocurrency Backed By?
Unlike fiat currencies (USD, EUR), which are backed by governments or central banks, cryptocurrencies are not backed by physical assets or governments. Instead, their value comes from different factors:

Scarcity (Supply and Demand)

1. Most cryptocurrencies, like Bitcoin, have a fixed supply, which means there will only ever be a limited number of coins (e.g., 21 million for Bitcoin). This scarcity often drives demand, especially if the cryptocurrency is seen as valuable or useful.

Utility

1. Cryptocurrencies with functional use cases, such as Ethereum (which powers smart contracts and DApps), have intrinsic value because they serve a purpose beyond just being a store of value. The more people use the network, the higher the demand for the cryptocurrency.

Network Security

1. The value of many cryptocurrencies is tied to the strength and security of their blockchain networks. The more secure and decentralized the network, the more valuable the cryptocurrency becomes. For instance, Bitcoin’s proof-of-work mechanism and massive global network give it credibility and security.

​
Community and Adoption

1. Cryptocurrencies are often supported by a community of developers, investors, and users who believe in the technology and its potential. The value of a cryptocurrency can be influenced by how widely it's adopted in the real world and the trust people place in the system. I am part of the Pi community, and it has been an amazing experience. I've met people from all over the world, I know my currency is safe, and I get to take part in new innovative strategies. 

Speculation

1. In many cases, cryptocurrency values are influenced by speculation. Investors might buy cryptocurrencies as an investment, hoping the price will rise, which can lead to volatility in the market. This speculative nature is what drives some of the dramatic price movements seen in the crypto space. On the other hand, there are people like me who don't speculate but enjoy the process. 

Again, in my opinion, cryptocurrency offers a vision of the future where decentralization, security, efficiency, and financial inclusion are key features of a new financial system. It works through blockchain technology, enabling person to person transactions and the use of cryptography for security. While not "backed" by physical assets like gold or fiat money, cryptocurrencies derive their value from scarcity, utility, and network security. 

You can ask the questions:

1. Is it volatile:  Yes.
2. Have people made money: Yes.
3. Should I invest: Only you can make that decision. Cryptocurrency has been around a while now and companies and governments are starting to accept it. All new things should be viewed with a practiced eye. All sides need to be weighed. 

And that, Lynene. Is the best I can do. For now, anyway.
