Cryptocurrency Introduction

 Summary

1. Cryptocurrency is a type of digital currency based on blockchain technology, which can realize peer-to-peer (C2C) transactions.

2. Bitcoin, Ethereum, and Tether are currently the leading cryptocurrencies in terms of market capitalization.

3. Cryptocurrency can be accessed in two ways: cryptocurrency wallet or trading platform. Although people often say that cryptocurrencies are “stored” in wallets, they are actually stored on the blockchain.

4. Cryptocurrency has several major characteristics, including decentralization, high transparency and non-tamperability.

What is a cryptocurrency?

Cryptocurrencies are a class of decentralized digital currencies that use cryptography to ensure security. It can operate independently of intermediaries such as banks and payment processors.

This decentralized nature can facilitate direct peer-to-peer (C2C) transactions between individuals. However, instead of physical wallets and bank accounts, people access their cryptocurrencies through unique cryptocurrency wallets or cryptocurrency trading platforms.

You may have heard people say that cryptocurrencies are “stored” in wallets. In fact, cryptocurrencies are not held in cryptocurrency wallets or trading platforms, but are always on the blockchain. Cryptocurrency exchanges hold the private keys to these funds, allowing users to access them.

Bitcoin is the first cryptocurrency and the most famous cryptocurrency. It was created in 2009 by a person or group under the pseudonym Satoshi Nakamoto. Since then, thousands of cryptocurrencies have emerged around the world, each with unique characteristics and uses.

Like traditional fiat currencies, cryptocurrencies can be used as a medium of exchange. However, over the years, cryptocurrency use cases have broadened significantly to include smart contracts, decentralized finance (DeFi), stores of value, governance and non-fungible tokens (NFT).

How do cryptocurrencies work?

We mentioned earlier that cryptocurrencies use cryptography for security purposes, but what does that really mean? Simply put, cryptocurrencies use advanced mathematical algorithms to secure transactions and protect data from unauthorized access or manipulation. These algorithms have two main functions: maintaining the privacy of user identities and verifying the authenticity of transactions.

Blockchain transactions are public and addresses (public keys) are pseudo-anonymous (although not completely anonymous). In other words, while the transaction is visible on the blockchain, the user behind the transaction is not easily identifiable. Cryptocurrencies achieve this by using cryptographic techniques such as hash functions and digital signatures.

Cryptocurrencies achieve autonomy through a distributed network of computers known collectively as a blockchain, which is essentially a decentralized digital ledger that stores transaction data on many specialized computers on the network.

Each such computer (also called a node) maintains a copy of the ledger, and there is a consensus algorithm that protects copies of the blockchain by rejecting false or inconsistent copies. This distributed architecture improves the security of the network because bad actors cannot exploit a single point of failure (such as a bank vault) to profit.

Cryptocurrencies allow individuals to transfer funds directly to each other. In a typical cryptocurrency transaction, the sender initiates the transfer by creating a digital signature using their private key. The transaction is then sent to the network, where nodes ensure the validity of the transaction by verifying the digital signature and ensuring the sender has sufficient funds.

After verification, the transaction is added to a new block and then added to the existing blockchain. This sounds complicated, but miners take care of these steps so users don’t have to worry.

What is unique about cryptocurrencies?

Cryptocurrencies introduce innovative features that differentiate them from traditional protocols and currencies, thereby profoundly impacting various ecosystems from finance to technology. Several main characteristics of cryptocurrencies include:

1. Decentralization

The decentralized architecture of cryptocurrency eliminates the need for a central authority. This allows for greater autonomy, with no single central agency or individual able to control or interfere with its operations.

2. High transparency and non-tamperability

Blockchain technology records all transactions on a transparent and tamper-proof ledger. Therefore, once a transaction is added to the blockchain, it can be viewed by anyone and cannot be changed or deleted.

3. Programmability

Many cryptocurrencies, such as ETH, are programmable, allowing developers to deploy smart contracts, create decentralized applications (dApps) and other innovative solutions on the blockchain. Additionally, since permissionless blockchains are open source, anyone can start deploying code on the blockchain and create their own dApps.

4. No borders

Cryptocurrencies are easily moved and traded globally, and people can use them for international transactions and remittances.

5. Predefined Token Supply

Many cryptocurrencies have a limited supply, meaning the teams behind them can only create a limited number of tokens. Over time, this deflation of cryptocurrencies could have a positive impact, as scarcity drives demand.

In contrast, fiat currencies typically experience inflation because central banks can print more money. With a limited supply, cryptocurrency inflation can be better controlled because the total number of tokens is predetermined.

Types of Cryptocurrencies

Among the many cryptocurrencies, there are four noteworthy currencies, namely Bitcoin (BTC) and popular altcoins — Ethereum (ETH), Litecoin (LTC) and Tether (USDT).

Bitcoin (BTC)

Bitcoin is the most popular cryptocurrency on the market. It uses a consensus mechanism called Proof of Work (PoW), where miners compete to validate transactions and keep the network running. Additionally, the supply of BTC is limited to 21 million coins, which makes it relatively scarce and helps maintain its value in the long term.

Ethereum (ETH)

ETH is the second most popular cryptocurrency, launched in 2015 by Vitalik Buterin and his team. In addition to being used for value transfer, it also enables programmability through smart contracts.

Like BTC, ETH initially used a PoW consensus mechanism, but it has since moved to a greener and more energy-efficient Proof of Stake (PoS) model. This shift allows users to verify transactions and secure the network by staking their own ETH rather than through nodes using computing power.

Tether (USDT)

USDT is a U.S. dollar-pegged stablecoin launched by Tether Limited Inc in 2014. A stablecoin is a cryptocurrency that is designed to maintain a stable value relative to a reserve asset, such as a fiat currency. In the case of USDT, each token is backed by an equivalent amount of the company’s reserves. Therefore, USDT offers the benefits of cryptocurrency while minimizing price volatility.

What is cryptocurrency market capitalization?

Cryptocurrency market capitalization is a metric used to determine the relative size and value of cryptocurrencies. It is calculated by multiplying the current price of a coin by the total number of coins in circulation. You may not have to do the math at all, though, as many cryptocurrency platforms will do it for you.

Cryptocurrency market cap is often used to rank cryptocurrencies, with a higher market cap generally indicating a more stable and widely accepted cryptocurrency. Conversely, a lower market cap generally indicates an asset is more speculative or volatile.

However, please note that this is just one of many factors to consider when evaluating a cryptocurrency’s potential. There are several other factors that should be considered when researching cryptocurrencies, such as technology, team, token economics, and use cases.

How to Invest in Cryptocurrencies Safely

Like other financial assets, investing in cryptocurrencies can be risky and can result in financial losses. Here are five must-have tips to help you buy and sell cryptocurrency more safely:

1. Do your own research

Its acronym is DYOR. Before investing in any cryptocurrency, be sure to understand the basics of blockchain technology, such as the different types of cryptocurrencies and market dynamics.

Books, blogs, podcasts, and online courses are all great places to start. You should also learn about the projects, teams, and technologies behind different cryptocurrencies in order to make an informed decision.

2. Start small and diversify your investments

The cryptocurrency market is volatile and unpredictable, especially for less popular coins. Therefore, it is wise to start investing with a small amount that does not hurt your vitality. This approach allows one to grow experience and better understand market trends without risking significant financial losses.

Diversification is also useful when investing in cryptocurrencies. Rather than focusing on a single cryptocurrency, investing in different cryptocurrencies can reduce your overall risk and increase your chances of long-term growth in your holdings.

3. Continue to participate

As the cryptocurrency landscape continues to change, investors should stay informed about news, technological advancements, and regulatory updates to be able to make timely decisions. Joining the crypto community is a great way to do this.

4. Choose a reputable cryptocurrency trading platform

In terms of security measures, the most important thing you should choose is a well-known and safe cryptocurrency trading platform for your crypto investments. For example, the world’s leading crypto asset trading platform: Deptoy

5. Carry out risk management

Before investing in any cryptocurrency, you must implement some risk management techniques. For example, please be sure to invest rationally and within your capabilities.

in conclusion

The cryptocurrency ecosystem represents a revolutionary approach to finance and technology. And how will cryptocurrencies develop in the future? The benevolent sees benevolence, the wise see wisdom.

Some people believe that Bitcoin will eventually replace gold and disrupt the existing financial system; some believe that cryptocurrencies will always be a secondary system and cannot go beyond the niche market. Some people firmly believe that Ethereum will evolve into a decentralized computer and become the mainstay of the new Internet.

The results are indeed unpredictable, and it is too early to even predict its development one year later. Nonetheless, we cannot deny that cryptocurrencies have already had a significant impact on various industries, and this impact is likely to expand further in the coming years.
