What Are Altcoins?
“Altcoin” is short for “alternative coin”, essentially, any cryptocurrency that isn’t Bitcoin.
When Bitcoin was created in 2009, it was the first decentralised digital currency. Since then, thousands of other coins have launched to address different needs, problems, or technical improvements. These are collectively known as altcoins.
Think of altcoins as the rest of the crypto ecosystem. They’re the competitors, collaborators, and niche specialists compared to Bitcoin’s “digital gold” status.
Some altcoins power platforms. Others are meant for faster payments, private transactions, or enabling smart contracts. Some support entire ecosystems like gaming, NFTs, or decentralised finance (DeFi).
Most Popular Altcoins You Should Know
Here’s a breakdown of widely used and respected altcoins (this guide excludes meme coins like Dogecoin or Shiba Inu).
1. Ethereum (ETH)
Already covered in detail in our ‘What is Ethereum’ guide, but worth a mention here.
Ethereum introduced smart contracts: automated agreements that live on the blockchain. It powers a huge amount of DeFi, NFTs, and decentralised applications (dApps). Many other altcoins are built on Ethereum’s blockchain.
2. Solana (SOL)
A high-speed blockchain known for ultra-low fees and fast processing times. It’s increasingly popular for dApps, DeFi projects, and NFTs, especially among users who find Ethereum too expensive or slow.
Why it matters: Fast, low-cost transactions make it appealing for global users sending money or using apps on the go.
3. Polygon (MATIC)
A “Layer 2” solution that works with Ethereum to make it cheaper and faster. Think of it as a helper blockchain.
Why it matters: Many Ethereum-based apps now use Polygon to improve speed and cost-efficiency, helpful for users with limited budgets or bad internet connections abroad.
4. Avalanche (AVAX)
Designed for custom blockchain deployments and DeFi scalability. It’s energy-efficient and ideal for financial products that want security without Ethereum’s cost.
5. Chainlink (LINK)
Not a currency for spending, but a key player in crypto infrastructure. It provides oracles: real-world data feeds to smart contracts (like prices, weather, or sports scores).
Why it matters: Many DeFi apps you might use rely on Chainlink behind the scenes.
6. Stellar (XLM)
Built for fast, affordable cross-border payments. Stellar targets the unbanked and underbanked.
Why it matters: If you’re living abroad or sending money back home, Stellar offers a compelling alternative to Western Union.
7. Monero (XMR)
A privacy-focused coin that hides transaction amounts, senders, and recipients. Not used for speculation as much, but popular among users who prioritise anonymity.
Caution: Due to its privacy features, some governments and exchanges restrict access to Monero.
8. Arbitrum & Optimism
These are “Layer 2” solutions like Polygon, helping scale Ethereum by processing transactions off-chain and syncing with the mainnet.
What Altcoins Are Used For
Altcoins aren’t just speculative tokens. They power a variety of real-world use cases that might matter to digital nomads and expats:
- Fast, cheap payments (e.g., XLM, SOL)
- Using decentralised apps like DeFi wallets, crypto lending, and trading platforms (e.g., ETH, MATIC)
- Accessing blockchain-based games and NFTs (e.g., SOL, AVAX)
- Running decentralised storage or VPNs (e.g., Filecoin, SiaCoin)
- Financial privacy in oppressive regions (e.g., XMR)
- Investing in innovative Web3 technologies (e.g., LINK, ARB)
Pros and Cons of Altcoins
✅ Benefits:
- More Utility: Many altcoins offer features Bitcoin doesn’t (e.g., smart contracts, speed, privacy).
- Lower Cost: Some are better suited for everyday transactions due to lower fees.
- Diversification: Useful for spreading your crypto risk.
⚠️ Watch out for:
- High volatility: Even more than Bitcoin in some cases.
- Less adoption: Fewer real-world services accept them.
- Security risks: Some altcoins are abandoned or become scams, always research.
How to Choose & Use Altcoins as a Digital Nomad or Expat
Here are some practical ways altcoins can benefit you:
1. Lower Fees for Transactions Abroad
If you’re moving funds across borders or using crypto payment cards, coins like SOL or XLM might save you money.
2. Use DeFi and Web3 Apps
You can borrow, lend, earn interest, or swap currencies directly from your crypto wallet using ETH, MATIC, AVAX, and more.
Example: You’re in Thailand and need cash fast. Instead of wiring money, you borrow against your crypto in minutes using a DeFi app like Aave or Compound.
3. Privacy and Financial Independence
If you’re living in a country with unstable banking or restrictive laws, coins like Monero may help you maintain financial freedom.
4. Invest in What You Use
As you explore Web3, you’ll find certain tokens become more relevant to your lifestyle, like using MATIC if your favourite apps run on Polygon.
Tips for Getting Started with Altcoins
- Use a trusted exchange like Binance to buy altcoins.
- Store securely: Use wallets like MetaMask or Ledger for long-term holding.
- Start with purpose: Don’t just buy random coins, choose ones that align with your needs.
- Watch the fees: Some networks can be pricey (e.g., Ethereum at peak times), so use Layer 2s where possible.
- Stay updated: The altcoin space evolves quickly, follow credible news sources, YouTubers, or blogs (like this one).
Final Thoughts: Are Altcoins Worth It?
Altcoins are a natural next step after understanding Bitcoin and Ethereum. They can be powerful tools, not just speculative assets, especially if you’re living an international, mobile lifestyle.
Explore them slowly. Learn how they work. Use them where it makes sense.
Altcoins may not be digital gold, but they are the digital Swiss Army knife of the crypto world.
