What Are Altcoins? Definition and Introduction
Altcoins, short for "alternative coins," refer to all cryptocurrencies except Bitcoin. Originally, the term described any coin introduced after Bitcoin. As Ethereum’s influence grew, some argue it now mainly covers coins other than Bitcoin and Ethereum.
Altcoins were developed to address perceived limitations in Bitcoin, introduce technical innovations, or serve new purposes within the blockchain ecosystem. In essence, altcoins offer variety and competition in the cryptocurrency world, diversifying what blockchain technology can achieve.
Key Notes
Altcoins encompass all cryptocurrencies except Bitcoin and provide a wide range of functionalities, including payment, smart contracts, stable value, privacy, and governance.
Many altcoins employ different consensus mechanisms and technologies, such as Proof of Stake and delegated validation, to address Bitcoin’s limitations and enable innovation.
The primary benefits of altcoins are diverse use cases, early investment opportunities, and technological advancements, while their key risks include high volatility, low liquidity, and susceptibility to scams.
Buying, storing, and securely managing altcoins requires careful exchange selection, strong wallet security, and ongoing project research to mitigate risks and maximise potential returns.
A Brief History of Altcoins
Bitcoin, launched in 2009, paved the way for digital currencies. Developers quickly sought to expand on its idea, which led to the rise of the first altcoins. Namecoin, created in 2011, aimed to decentralise internet domain registration. Litecoin followed, improving transaction speed and algorithm efficiency.
These early projects inspired a wave of innovation, each with a unique value proposition, technology, or community. Some focussed on scalability, privacy, or new smart contract features, driving rapid evolution in the cryptocurrency space.

How Are Altcoins Different from Bitcoin?
Blockchain technology and consensus mechanisms
Altcoins frequently experiment with blockchain technology distinct from Bitcoin’s design. Bitcoin relies on Proof of Work (PoW) for security and consensus. In contrast, many altcoins have introduced alternatives such as Proof of Stake (PoS), Delegated Proof of Stake (DPoS), and Proof of Capacity.
PoS systems—used by Ethereum since its upgrade—allow users to validate transactions based on holdings rather than computational effort. This reduces energy consumption and can increase transaction speeds. DPoS, used by TRON, involves a smaller set of trusted validators for efficiency. Proof of Capacity, seen in coins like Burstcoin, uses disk space for mining rather than processing power.
Function and utility
Altcoins vary greatly in functionality beyond serving as digital money. Some enable complex programmable transactions, like Ethereum’s smart contracts. Others, such as stablecoins, peg their value to traditional assets for price stability.
Privacy-focused coins—like Monero—emphasise anonymity. Utility tokens grant access to a platform’s services, while governance tokens provide voting rights for project decisions. This functional diversity makes altcoins significant players in the blockchain revolution.
Main Types of Altcoins
The cryptocurrency sector features a wide variety of altcoins, each belonging to distinct categories based on their purpose and design.
Payment coins
Payment coins, such as Litecoin and Ripple (XRP), are designed as digital money for transactions. They strive to improve speed and scalability for everyday use cases, offering efficient alternatives to Bitcoin’s transaction structure.
Stablecoins
Stablecoins, including Tether (USDT) and USD Coin (USDC), aim for price stability by pegging their value to fiat currencies. These tokens are commonly used in trading, allowing users to move funds without exposure to crypto market volatility.
Security tokens
Security tokens represent ownership of real-world assets, such as shares in a company or property. They are often regulated and designed for tokenising traditional financial instruments, bringing blockchain efficiencies to established markets.
Utility tokens
Utility tokens serve as the lifeblood of specific blockchain projects, granting access to services or features within a given platform. For example, Binance Coin (BNB) reduces trading fees on its native exchange.
Meme coins
Meme coins, like Dogecoin, originate from internet culture and viral memes. Although often launched as jokes, their strong communities and widespread attention have driven significant market activity.
Governance tokens
Governance tokens empower holders to influence a project's development and decision-making process. These tokens facilitate transparent voting on updates or changes, a hallmark of decentralised finance.
Equity tokens
Equity tokens are a new category, representing ownership rights or shares in a blockchain-based organisation. They blend traditional equity with the programmability and liquidity of tokens.

Ethereum (ETH): Leading platform for smart contracts and decentralised applications.
Litecoin (LTC): Fast and efficient payment-focused coin, a technical fork of Bitcoin.
Ripple (XRP): Specialises in cross-border payments and financial institution settlements.
Tether (USDT): Most widely used stablecoin, pegged to the US dollar.
Binance Coin (BNB): Used for fee reduction and a variety of services on the Binance ecosystem.
Cardano (ADA): Emphasises research-driven development and sustainable scalability.
Solana (SOL): Known for extremely fast and low-cost transactions.
Dogecoin (DOGE): Born from internet culture, now with a large, enthusiastic community.
TRON (TRX): Focused on decentralised content sharing and entertainment.
Monero (XMR): Provides strong privacy features for confidential transactions.
IOTA (MIOTA): Unique architecture for the Internet of Things, using its Tangle network rather than traditional blockchains.

How to Buy Altcoins: A Simple Step-by-Step Guide
Choose an exchange or broker
Start by choosing a reputable cryptocurrency exchange or broker that lists your desired altcoin. Check all ICONOMI's listed assets.
Peer-to-peer platforms enable direct transactions between users. Always check the exchange's security record, regulatory compliance, and Know Your Customer (KYC) policies.
Create an account and deposit funds
Register with your chosen platform, providing identity verification and contact information. Deposit funds through bank transfer, credit card, or by transferring cryptocurrency from another wallet. Some exchanges accept only crypto deposits, while others support fiat money.
Placing a buy order for altcoins
Search for the altcoin you wish to purchase, using its symbol (such as ETH for Ethereum). Choose between market and limit orders depending on your trading preference. Once bought, you may store altcoins directly on the exchange or withdraw them to an external wallet for enhanced security.
Storing your altcoins safely
Store your altcoins in a secure crypto wallet to reduce the risk of theft. Software wallets are suitable for everyday use, while hardware wallets offer enhanced offline security for long-term holdings. Custodial wallets are managed by third parties; non-custodial wallets put security into your hands. Always secure your wallet with strong passwords and backup your recovery phrases in a safe location.
The Role of Altcoins in the Cryptocurrency Ecosystem
Altcoins are fundamental drivers of innovation in blockchain and cryptocurrency. They challenge Bitcoin's dominance by introducing new technologies, consensus mechanisms, and business models. Many industries—finance, gaming, art—have been reshaped by altcoins, especially through decentralised finance (DeFi) and non-fungible tokens (NFTs). By enabling use-case diversity, altcoins bring competition, which benefits users and accelerates sector growth.
The Future of Altcoins: Trends and Potential
The altcoin sector is evolving rapidly. Regulatory scrutiny continues to increase, particularly for security tokens and projects conducting Initial Coin Offerings (ICOs). Many altcoins will fade as markets mature; only projects with robust technology, strong communities, and clear real-world value are likely to thrive.
Trends such as cross-chain compatibility, enhanced privacy, and lower transaction fees may define the next generation of successful altcoins. Continued innovation is expected to power blockchain adoption well beyond the cryptocurrency sphere.
