Summary
Cryptocurrency is a digital currency based on blockchain technology that enables peer-to-peer (P2P) transactions.
Bitcoin, ether, BNB, and USDT are examples of top cryptocurrencies by market capitalization.
Cryptocurrencies are accessed through wallets or crypto exchanges. Although people often say that crypto is “stored” in a wallet, crypto is actually stored on a blockchain.
Cryptocurrencies have certain characteristics, including decentralization, transparency, and immutability.
What is Cryptocurrency?
Cryptocurrencies are decentralized digital currencies that use cryptography for security. Crypto can operate independently without intermediaries such as banks and payment processors.
This decentralized nature facilitates direct peer-to-peer (P2P) transactions between individuals. However, instead of physical wallets and bank accounts, people access their cryptocurrency through unique crypto wallets or crypto exchanges.
You may have heard people say that crypto is “stored” in a wallet. However, cryptocurrencies don't actually exist in crypto wallets or exchanges — in fact, they always reside on the blockchain. Crypto exchanges have private keys that allow users to access those funds.
The first and most famous cryptocurrency was Bitcoin which was created in 2009 by a person or group with the pseudonym Satoshi Nakamoto. Since then, thousands of cryptocurrencies have emerged, each with unique characteristics and goals.
Just like fiat currency in general, cryptocurrency can be used as a medium of exchange. However, the uses of cryptocurrencies have expanded significantly over the years to include smart contracts, decentralized finance (DeFi), stores of value, governance, and non-fungible tokens (NFTs).
How Do Cryptocurrencies Work?
We've mentioned that cryptocurrencies use cryptography for security purposes, but what does that mean? Simply put, cryptocurrencies use advanced mathematical algorithms to secure transactions and protect data from unauthorized access or manipulation. This algorithm has two main functions: maintaining the privacy of user identity and verifying the authenticity of transactions.
Blockchain transactions are public and addresses (public keys) are pseudonymous, although not completely anonymous. In other words, although transactions are visible on the blockchain, the users behind them are not easily identified. Cryptocurrencies achieve this by using cryptographic techniques such as hash functions and digital signatures.
Cryptocurrencies achieve autonomy through a distributed network of computers collectively called a blockchain which is essentially a decentralized digital ledger that stores transaction data on various specialized computers on the network.
Each of these computers — also called nodes — keeps a copy of the ledger, and a consensus algorithm maintains a copy of the blockchain by ensuring that fake or inconsistent copies are rejected. This distributed architecture increases network security because there is no single point of failure, such as a bank vault, that criminals can exploit.
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 his or her private key. Then, the transaction is sent to the network where nodes validate it by verifying the digital signature and ensuring that the sender has sufficient funds.
Once verified, the transaction is added to a new block which is then added to the existing blockchain. Even though it seems complicated, miners take care of these steps so that users don't have to worry about them.
What Makes Cryptocurrency Unique?
Cryptocurrencies have influenced various ecosystems, from finance to technology, by bringing innovative features that differentiate them from traditional protocols and currencies. Some of the unique aspects of cryptocurrencies include:
1. Decentralization
The decentralized architecture of cryptocurrencies eliminates the need for a central authority. This allows for greater autonomy, as well as reduced vulnerability to manipulation or control by a single entity.
2. Transparency and immutability
Blockchain technology records all transactions on a transparent and tamper-proof ledger. That way, once added to the blockchain, transactions can be seen by anyone and cannot be changed or deleted.
3. Programmability
Most cryptocurrencies, such as ETH, are easy to program, so developers can deploy smart contracts to create decentralized applications (DApps) and other innovative solutions on top of the blockchain. Additionally, because permissionless blockchains are open source, anyone can start implementing code on top of them and create their own DApps.
4. Nirbat
Cryptocurrencies are easily transferred and exchanged globally, so people can use them for international transactions and remittances.
5. Supply the specified coins
Most cryptocurrencies have a limited supply of coins, meaning the team behind them will only create a limited number of coins. This deflationary aspect of cryptocurrencies could potentially be a positive thing over time, as scarcity will drive demand.
In contrast, fiat currencies are often inflationary because central banks can print more money. However, with limited supply, crypto inflation can be better controlled because the total number of coins is fixed.
Types of Crypto Currency
Among the myriad of cryptocurrencies, four prominent examples include Bitcoin (BTC) as well as popular altcoins ether (ETH), Binance Coin (BNB), and Tether (USDT).
Bitcoin (BTC)
BTC is the most popular cryptocurrency. This cryptocurrency uses a consensus mechanism called proof-of-work (PoW), which requires miners to compete to validate transactions and keep the network running. Additionally, BTC's limited supply of 21 million coins makes it relatively rare and helps it maintain its value over time.
Ether (ETH)
ETH is the second most popular cryptocurrency launched in 2015 by Vitalik Buterin and his team. In addition to transferring value, ETH allows programmability through smart contracts.
Like BTC, ETH originally used a PoW consensus mechanism, but has switched to a more environmentally friendly and energy efficient proof-of-stake (PoS) model. This switch has allowed users to validate transactions and secure the network by staking ETH rather than via nodes using computing power.
BNB
BNB (short for Build and Build), previously called Binance Coin, was introduced in 2017 by cryptocurrency exchange Binance as an ERC-20 token on the Ethereum blockchain. In 2019, BNB migrated to its own blockchain, namely BNB Chain, as the BEP-2 token.
Binance Smart Chain (BSC; now called BNB Smart Chain) was then created, and the BNB cryptocurrency currently exists on BNB Chain as a BEP-2 token and BSC as a BEP-20 token. It is also worth noting that BNB Chain consists of two chains: BSC which is EVM compatible, as well as BNB Beacon Chain (formerly called Binance Chain) which includes governance, staking, and voting.
BNB Chain provides an environment for creating smart contracts and DApps, and has lower transaction fees and faster processing times than other blockchains.
BNB has a variety of uses, including paying transaction fees on BNB Chain and trading fees on Binance, participating in token sales, and staking for network validation on BNB Chain. Binance also uses a periodic token burning mechanism that limits the overall supply of BNB.
Tether (USDT)
USDT is a USD-pegged stablecoin launched in 2014 by Tether Limited Inc. Stablecoins are cryptocurrencies designed to maintain consistent value compared to reserve assets, such as fiat currencies. In the case of USDT, each token is backed by an equivalent amount of assets held in the company's reserves. As a result, USDT offers the benefits of cryptocurrency while minimizing price fluctuations.
What is Hood. Crypto Market?
The term “hood. crypto market” is short for “cryptocurrency market capitalization,” which is a metric used to determine the relative size and value of a cryptocurrency. The calculation is the current coin price times the total number of coins in circulation. However, you may not even need to calculate it as most cryptocurrency platforms will calculate it for you.
Hood. Crypto markets are often used to rank cryptocurrencies. A higher market capitalization generally indicates a more stable and widely accepted cryptocurrency. Conversely, a low market capitalization usually indicates a more speculative or volatile asset.
However, please note that this is just one of many factors to consider when evaluating a cryptocurrency's potential. Several other factors, such as technology, team, tokenomics, and usability, should also be considered when researching cryptocurrencies.
How to Invest in Crypto Safely
Just like other financial assets, investing in cryptocurrencies may be risky and result in financial loss. Here are five important tips for safer buying and selling of cryptocurrency:
1. DYOR
The acronym DYOR stands for "do your own research" or do your own research. You should understand the basics of blockchain technology — such as the different types of cryptocurrencies and market dynamics — before investing in any cryptocurrency.
Books, blogs, podcasts, and online courses are great starting points. You should also learn about the projects, teams, and technology behind various cryptocurrencies in order to make informed decisions.
2. Start with small investments and diversify
The crypto market can be volatile and unpredictable, especially for less popular coins. Therefore, starting with a small investment that will not drain your pockets is a wise move. This approach allows you to gain experience and develop a better understanding of market trends without incurring major financial losses.
Diversification can also be beneficial when investing in cryptocurrencies. Rather than focusing on a single cryptocurrency, investing in multiple cryptocurrencies can reduce overall risk and increase the opportunities for long-term growth for your holdings.
3. Stay involved
As the cryptocurrency landscape is constantly changing, you need to stay on top of news, technological advances, and regulatory updates to make timely decisions. Joining a crypto community is a great way to do this.
4. Choose a reputable cryptocurrency exchange
Choosing a well-known and safe cryptocurrency exchange for your crypto investments should be a priority when it comes to security measures. The right crypto exchange can be found by researching various options and then comparing fees, customer support, interfaces, and available cryptocurrencies.
5. Implement risk management
Before investing in cryptocurrency, you should implement some risk management techniques. For example, investors may only invest funds whose losses can be borne. Additionally, setting stop-loss orders to limit potential losses and taking profits at specified levels to secure profits can make a big difference.
Conclusion
The cryptocurrency ecosystem represents a revolutionary approach to finance and technology. However, the future of cryptocurrency depends on the people you talk to.
Some parties believe that bitcoin will replace gold and overhaul the existing financial system, while others argue that cryptocurrencies will always be a secondary system and a niche market. There are also those who believe that Ethereum will become a decentralized computer that will function as the backbone of the new Internet.
Although the possible outcomes are numerous, it is too early to determine what will happen even a year from now. Nonetheless, the clear impact of cryptocurrencies on various industries cannot be denied, which will likely continue to grow in the years to come.
