Everything About Altcoins: What Makes Them Different from Bitcoin

Bitcoin has sent a powerful blow, a decentralization energy shot that sparked a global discussion about digital money. After that, "altcoins" were born – these are Bitcoin's alternatives which have boosted exponentially since that time. An abundance of them are setting up a future disruptive innovation akin to the revolutionary Tesla of the car industry. They fuel the countless DeFi experiments that are still at their infancy. Nevertheless, before diving straight into that confusing world, it would be better if we first got to know what those altcoins are really like.

What Is an Altcoin?

Altcoin. Just a coin. "Alternative coin." It means that it is not Bitcoin. Bitcoin was the first, the one who paved the way for the whole blockchain concept back in 2009. The whole bunch of new ones that appeared afterwards is still referred to under this broad 'altcoin' umbrella.

The initial start of these alternatives appeared in 2011. Litecoin (LTC) was the leader among the followers, aiming to be a lighter and faster version of Bitcoin. The goal was usually to follow the Bitcoin plan and change it. It could have had a different mining algorithm, shorter block times, bigger coins supply, or new privacy features. Some altcoins are direct "forks" of Bitcoin. They took the software code of Bitcoin and then they decided to develop their own way. Others were created from scratch, with new blockchains, various honesty keeping methods, and their own rules.

Altcoins vs. Bitcoin

Bitcoin is the undisputed and market leader. The network of Bitcoin is currently capable of approximately 7 transactions per second on average with a block time of 10 minutes. The energy consumption of Bitcoin is on the level of that of small countries.

Altcoins are looking for different ways to achieve the same result. Ethereum enables programmable money via the implementation of smart contracts. Solana is speed-focused with a 50,000+ TPS rate. Cardano is committed to academic research and the formal verification process.

Key differences between Bitcoin and Altcoins

Bitcoin is still the most recognized brand and the first-mover. Institutional investors are comfortable with Bitcoin's simplicity and its proven history. Altcoins are appealing to those developers and users that have the features they need, which Bitcoin doesn't provide.

The bond is still mutually beneficial even though there is rivalry. Bitcoin's market share has an impact on altcoin prices. The innovations of the major altcoin sector eventually lead to Bitcoin developments. Both gain from the additional crypto adoption.

Types of Altcoins

The term "altcoin" is a big tent, sheltering a wild collection of digital beasts. To get a grip, you gotta sort them into rough categories. Here are the main species you'll encounter in this digital zoo. Keeping up with these types and their market movements is something crypto news sites, maybe even one like CoinMinutes, would track.

Different types of altcoins

1. Platform Coins

These are the main base layers, the digital earth over which the main applications and tokens get their energy. In fact, they could be referred to as the OS of the decentralized internet. The platforms’ native coins are indispensable. The users do them to make the payment for the transaction fees. The ones which are used to initiate a smart contract. In most cases, the ones which are used for staking in Proof-of-Stake networks. They shall be the ones, enabling their respective ecosystems to operate.

Ethereum (ETH) is the leading entity here. Its blockchain is the place where a great number of different tokens (like ERC-20s and NFTs) and the thousands of decentralized applications (dApps) live. Other important platform coins can be Solana (SOL), noted for its high transaction speed; Cardano (ADA), which is famous for its carefully research-based development; and Polkadot (DOT), which is striving to make different blockchains talk to each other (interoperability).

2. Payment Coins

These altcoins are purely designed to be superior money in the digital sense. Their primary objective is to enable transactions that are quick, cheap, and efficient, typically across borders. They usually seek a way to solve problems that Bitcoin has, such as the speed of transactions, the price, or scalability for the daily use of the cryptocurrency.

Litecoin (LTC) is the first one that was launched for the aim to have a lighter and faster Bitcoin alternative. Bitcoin Cash (BCH) was a breakout from Bitcoin of which the main concept was that big blocks would be used to process more transactions. Dash also offers features that are for the speedily and secretly conducted transactions.

3. Stablecoins

The volatility of the crypto market is extremely well-known and usually expressed in the form of a roller coaster ride. The stablecoins, however, do not retell the same story of the crypto world. The key characteristic of this altcoin is its being structured in such a way as not to have a considerable departure from the very first value. This is most often done by linking their prices to another asset, which is usually a major fiat currency such as the U.S. dollar. The stablecoins in the image are those that provide an absolutely safe reserve of the asset they are pegged to. Apart from that, they may be of the algorithmic kind or use the collateral of other cryptocurrencies to keep the price at the peg.

Tether (USDT) and USD Coin (USDC) are the largest stablecoins in total. Each of the two units is made up of two such units that have the same value as the U.S. dollar. They are the most popular trading tools among crypto traders on the exchanges. In such cases, they may be used as a temporary safe, a means of payment, and a bridge between the worlds of traditional and crypto if the market is at its most volatile.

4. Utility & Governance Tokens

In most cases, these are the tokens that are planned to be used as the primary means of payments for a certain blockchain project, specific ecosystem, or a decentralized application.

• Utility Tokens: The easiest way is to think of them as the digital keys that give you access, a discount, or the points of a loyalty program. They provide users the right to be the user of a particular product, service, feature, or function on a platform.

Filecoin (FIL) is the utility token that is built to serve as the means of payment to those who are storage providers of the data that is running on the decentralized Filecoin network. Basic Attention Token (BAT) is a part of the Brave browser, where it is possible both to hand over the users for watching ads and to donate to the creators of the content.

• Governance Tokens: The tokens with which the owners can, for example, decide who gets the most votes and, therefore, have the most influence on the future development, the changes, and the operational conditions of a decentralized protocol or organization—usually a Decentralized Autonomous Organization (DAO)—that are the voting rights.

The main governance token of Uniswap decentralized exchange is Uniswap (UNI). The holders of UNI are those who decide which proposals will be put to a vote and which will not. Aave (AAVE) tokens are the ones that give to the holders the possibility to take part in the governing of Aave, the lending, and borrowing protocol.

5. Meme Coins & Experimental Assets

Meme coins are at the wilder and more unmanageable end of the spectrum of altcoins. The same things that make rational financial analysts raise their hands in frustration are the reasons that they, however, secretly add these assets to their portfolio.

• Meme Coins: The origin of these digital currencies is, most of the cases, internet jokes, memes, or viral social media trends. The price of those coins is most likely to be influenced by community enthusiasm, hype cycles, and endorsements of the influential figures, instead of a solid underlying technology or utility. After the introduction of the leading coin, some meme coin projects might become more attractive to holders by, for example, creating ecosystems or using cases.

It is a commonly accepted fact that Dogecoin (DOGE), i.e., a coin whose origin was a joke about a Shiba Inu dog, was the first meme cryptocurrency. Then the Shiba Inu (SHIB) appeared, which was to be the second most dominating force in that market. Basically, those coins are highly speculative.

• Experimental Assets: The term is used to refer to the things that are a total novelty, completely untried or have only been on the market for a very short time in ultra-niche sectors. For example, a gaming platform-based digital currency, an original digital art project, a new method of community funding, or an experimental tech concept that is still in the process of being adopted can be referred to as such. Such assets are of high speculation and mostly they receive the hot and cold reactions from the supporters and the few hobbyists, respectively.

Top 10 Altcoins in 2025

By mid-2025 the crypto market is jam-packed with ambitious, overhyped, and sometimes brilliant projects. The list is absolutely not a recommendation to anyone to make a money decision. Just a glance at the altcoins that are either gaining popularity, have reached a crucial development phase, or have already established a strong community and created a use-case. In other words, an observation-based field guide, not a treasure hunting map. The rankings are questionable, and nobody can predict the future.

Top 10 altcoins in 2025

1. Ethereum (ETH)

Ethereum is the uncontested monarch among smart contract platforms. Its transition to Proof-of-Stake (known as "The Merge" in 2022) has reduced the electricity consumption of the network drastically. Scalability is a huge problem for them, however, they still push the envelope and are the first in DeFi, NFT, dApp areas. Its large developer community and network effects are enormous.

2. Solana (SOL)

The Solana network is a blazing fast and very efficient blockchain with no delays and no bottlenecks as measured by throughput and latency. Solana has established itself as the go-to platform for DeFi, the conventional financial world, and NFT market. Though a few technical issues occurred in the latest volatile periods, the Solana ecosystem remains firm, and, by all indications, it is going to be this way for a long time.

3. Cardano (ADA)

Cardano is a platform which is a research-driven approach, and it also focuses on peer-reviewed academic development. The gradual transition to smart contracts and the concentration on environmental aspects, welfare and governance has won it a very loyal community. The developments of its Hydra scaling solution and Voltaire governance era are very important.

4. Polkadot (DOT)

Polkadot was developed as a network that allows different blockchains to communicate with each other. The term Polkadot "parachain" refers to those blockchains that are technically separate but can establish a secure connection and function within the Polkadot network, thus, being able to interact with each other.

5. Chainlink (LINK)

Decentralized oracle network that is the best in the market. The contracts on the blockchain are volatile and need data from the real world that is reliable—price feeds, weather info, sports scores. Chainlink is thus the bridge that connects the two, resulting in a necessary piece of infrastructure, not just for DeFi but also for other applications.

6. Avalanche (AVAX)

Avalanche is a platform that puts a lot of emphasis on performance, capability, and modularity via the architecture of its “subnet." This system is therefore enabling the projects to launch their own validated blockchains that will be exactly fitted to their needs. Good in DeFi and suitable for attracting the enterprise's interest.

7. Polygon (MATIC)

A number one Layer 2 scaling solution for Ethereum that is most widely used. Polygon provides various instruments, including its PoS sidechain, zk-rollups (like Polygon zkEVM), and optimistic rollups, to allow Ethereum to take up more transactions at a higher speed and at a lower cost. Is a key player in the Ethereum ecosystem.

8. USD Coin (USDC)

USD Coin is fiat-stablecoin number one that is one-to-one with the US dollar. This stablecoin is mainly focused on the regulatory area and its reserves, which are the Circle, are very transparent. It is the basis of DeFi swaps, lending, and the bridge between traditional finance and crypto. The only stability and good reputation of the coin have been the leading factors for it to remain the first place.

9. Dogecoin (DOGE)

Talking about Dogecoin, the first and the most significant meme coin is still going strong in its place. Back then, it was just a joke and didn't have any considerable value in 2013. What is most valuable to it now is an energetic community of people and some celebrities who are always full of praise for it. By the way, it is a PoW blockchain and, quite unexpectedly, the only one. The feeling and the community are the only things that keep it going, yet it is not at all beaten from the aspect of the culture.

10. Uniswap (UNI)

Uniswap's governance token is one of the biggest and most powerful decentralized exchange (DEX) - Uniswap. DEXs are the engines of DeFi ecosystem, as users can trade crypto-assets directly from their wallets without the need for middlemen. The innovation in the automated market maker (AMM) mechanism has been the main factor behind Uniswap's staying at the top.

How Altcoins Change DeFi

Altcoins aren't just a sideshow to Bitcoin. Many of them are the cogs, wheels, and fuel for the burgeoning, and often bewildering, world of DeFi. They’re not just for speculating. They’re being used as tools to try and build a new kind of financial plumbing, one that supposedly cuts out the old gatekeepers like banks and brokers. It’s a grand, messy, and potentially transformative experiment.

What Is DeFi?

DeFi is short for "Decentralized Finance". The main idea is just the transfer of the services that your local bank or a Wall Street professional provides you and then recreating those services on the blockchain. The covered services are lending, borrowing, trading, interest earning, insurance, derivatives, and so on. Namely, it means smart contracts, which are short programs that are always doing the part of the contract that was agreed upon if the given conditions are fulfilled. Of course, no human intervention is needed.

The Role of Altcoins in DeFi

Bitcoin is not the main player in the DeFi game. Its blockchain is far slower compared to other blockchains and is not aimed at conducting the complicated smart contract operations needed by DeFi apps. That is where altcoins come to play. They mostly build on the versatile smart contract platforms. They are the wheels and the fuel of the DeFi engine.

Altcoins have different roles in DeFi

• Platform Coins: They are the native coins of the Layer 1 blockchains, where most of the DeFi applications are built and executed. Users need these coins to pay transaction fees which are required to interact with the DeFi protocols. Ethereum is the major platform for DeFi, but the competitors are always there.

• Stablecoins: The protocol is the base of DeFi. The significance of stablecoins. A stable unit of account is necessary in order to lend or borrow as well as to give liquidity while trading pairs. If your main assets become volatile up to 20% per day, you cannot create a financial system with predictable behavior. Those which are usually equal to the US dollar in value are the main players in the stablecoin market, and they are responsible for this vital part of their relative price stability.

• Governance Tokens: Most DeFi protocols are decentralization-oriented, hence setting a goal for the decentralized governance, where the evolution of the protocol (e.g., upgrades, fee changes, risk parameters, etc.) is done only by the community of token holders. These governance tokens give holders voting power. For example, holding UNI tokens allows you to vote on proposals related to the Uniswap decentralized exchange.

• Liquidity Pool (LP) Tokens: Users who repurchase their crypto assets into the liquidity pool of a decentralized exchange or a lending platform typically get LP tokens as a receipt. These LP tokens communicate their share of that pool and thus, they can also deposit them to other protocols for a certain period of time called "yield farming" in order to receive additional incentives.

• Wrapped Tokens: They are altcoins that serve as a vehicle for assets from one blockchain to another. A case in point is WBTC, a token of the ERC-20 standard running on the Ethereum blockchain and having Bitcoin as the backing with a ratio of 1:1. This case allows the Bitcoin holders to unleash the value of their BTC in Ethereum's vast DeFi ecosystem.

• Native DeFi Protocol Tokens: Most DeFi apps not only allow users to govern through issuing the tokens but also they these tokens as the means to pay fees at a discount, get better rewards, or use other platform-specific utilities.

DeFi would be a very different place without such a diverse ecosystem of altcoins that are specialized. Altcoins have many functions such as the foundational infrastructure, the reliable mediums of exchange, the community governance mechanisms, and the various financial instruments that energize these new forms of decentralized markets. The interaction of these tokens is the key if you want to catch up with Defi trends, and that is just what you can find on sites like CoinMinutes.

The Future of DeFi and Altcoins

One thing that is very clear is that decentralized finance (DeFi) and altcoins are the closest things to a power duo in the crypto world as altcoins are the main drivers which fuel the DeFi ecosystem. Neither one can exist independently from the other. Their fortunes may still be uncertain and full of unpredictable twists and turns.

• Innovation & Competition: A place where altcoins live is a very hot one, with galing competition that never dies. New Layer 1 platforms, Layer 2 scaling solutions, and DeFi protocols are consistently coming up, each of them is asserting that they will provide the best service in terms of speed, cost, security, or features. This competitive pressure fuels rapid innovation in DeFi.

• Scalability Solutions: The main blockchain platforms have to be able to manage high transaction volumes without causing congestion and excessive fees, for DeFi to gain a wider acceptance. The growth and continuous adaptation of Layer 2 scaling solutions (such as the ones provided by Polygon) and the increasing scalability of new Layer 1 altcoin platforms (such as Solana or Avalanche) are pivotal.

• Regulatory Landscape: The unknown that has the largest scale. Financial authorities including governments and regulators are still working hard to come up with the right approach for dealing with DeFi and of the cryptocurrencies. The regulations that are yet to come and which will provide the solution of the stablecoins, decentralized exchanges, AML, and investor protection problems will be of vital importance for the DeFi sector.

• Interoperability: The capacity of different blockchains and their respective altcoins to be able to understand each other and transfer assets to each other without barriers is the biggest problem here and certainly a crucial aspect of the development of the industry. Polkadot and Cosmos, besides cross-chain bridge technologies, are implementing their ideas. It is likely that real interoperability will unleash great opportunities for DeFi.

• Security & Risk Mitigation: Stealing, faking, and vulnerabilities in the smart contracts are the main issues in the DeFi market, and it leads to a money problem that is really huge in the losses caused to investors. The solution is definitely in security audits with higher robustness, better development practices of smart contracts, decentralized insurance solutions, and users' raising awareness of the dangers.

• User Experience (UX): If DeFi has a chance to develop beyond the circle of people who are well acquainted with crypto, it must become much more user-friendly and intuitive. Don't be surprised if the requirement to handle multiple wallets, protocols, and altcoins dull the situation and cause a big challenge for the newbies. The innovations in UX / UI will be very important.

The future of altcoins is unpredictable

DeFi is still at its toddler phase, and it is undergoing a phase of experimentation. We'd say the internet in the 90s when it was still new and full of great prospects but was still awkward, risky, and not very efficient for regular users. The altcoins that constitute its core are the instruments and raw materials for this unceasing building work. A number of them will knit into the fabric of the future financial system. More, however, will find themselves dumped in the e-waste heap.

The Bottom Line

Altcoins have changed considerably. Initially, they were currencies similar to Bitcoin but now, they have become various tools for specific job performance. The market has eliminated many failed projects and at the same time, has been a source of innovations in smart contracts, payments, and decentralized finance.

The altcoin sector is going to keep on changing very fast. The investors who make good decisions are more interested in fundamental value than in the movement of prices in the short term. CoinMinutes numbers indicate concentrating on platforms with real usage and technical competence.
