What are altcoins and why do they matter
Altcoins are every cryptocurrency besides Bitcoin. Learn about the main categories, how they relate to market cycles, and why they matter for copy trading investors.
Bitcoin was the first cryptocurrency, launched in 2009. Every cryptocurrency that came after it is called an altcoin — short for "alternative coin." Today there are thousands of them, each with different purposes, technologies, and risk profiles. Understanding what altcoins are and why they exist is a fundamental step for anyone entering the crypto space.
Why altcoins exist
Bitcoin proved that decentralized digital money could work. But its design prioritizes security and simplicity over speed and flexibility. Developers saw opportunities to build cryptocurrencies that solved different problems: faster transactions, programmable contracts, private payments, decentralized applications, and more. Each altcoin represents a different bet on what blockchain technology can achieve.
Some altcoins compete directly with Bitcoin as a store of value or medium of exchange. Others serve entirely different purposes — powering decentralized finance platforms, enabling digital art ownership, or connecting real-world data to blockchain networks.
The main categories
Altcoins generally fall into a few broad categories. Layer-1 blockchains like Ethereum, Solana, and Avalanche are independent networks that host their own ecosystems of applications. Stablecoins like USDT and USDC are pegged to the US dollar and serve as the cash equivalent of the crypto world — you can learn more about them in our guide to stablecoins.
There are also utility tokens that power specific platforms (like Chainlink for data oracles or Uniswap for decentralized trading), meme coins driven largely by community enthusiasm (like Dogecoin and Shiba Inu), and governance tokens that give holders voting rights over protocol decisions.
Altcoins and Bitcoin dominance
The crypto market often moves in cycles. When Bitcoin rallies strongly, its share of total market capitalization — known as Bitcoin dominance — rises, and altcoins may underperform. When dominance falls, capital tends to flow into altcoins, sometimes producing outsized returns. This dynamic is a core part of altcoin investment strategy.
Understanding these cycles helps investors decide when to hold Bitcoin, when to rotate into altcoins, and when to sit in stablecoins. It is not about picking sides — it is about reading the market environment.
Higher reward, higher risk
Altcoins can deliver spectacular returns during bull markets. It is not uncommon for smaller tokens to gain several hundred percent in weeks. But the reverse is equally true: many altcoins lose 80–95% of their value during downturns, and some never recover.
The smaller the coin's market capitalization, the more volatile it tends to be. Liquidity is thinner, price swings are sharper, and the risk of project failure is real. This is why diversification matters even more in crypto than in traditional markets.
How copy trading relates to altcoins
For investors who want exposure to altcoins but lack the time or expertise to research individual tokens, copy trading offers a practical solution. Experienced master traders monitor market conditions, rotate between assets, and manage risk on your behalf. You benefit from their altcoin knowledge without needing to become an expert yourself.
The key is choosing traders who demonstrate consistent, risk-adjusted performance — not just headline returns. Always check what their followers actually earned, since the master trader's results and the copier's results are not always the same.
