When you first step into the world of cryptocurrency, you’ll likely encounter a wide array of coin names—from Shiba Inu to Monkey tokens. Besides Bitcoin, you may also have heard the term "altcoin." While it might sound like these are counterfeit products, many altcoins hold real value and potential. So, how can you strategically invest in altcoins? What risks should you be aware of? In this guide, we’ll also introduce you to the "Altcoin Season Index"—a handy tool to help gauge the best time to enter the market.
Compared to Bitcoin, which often reaches prices in the tens of thousands of dollars, many altcoins are relatively affordable, making them more accessible to new investors.
What Are Altcoins?
Simply put, any cryptocurrency other than Bitcoin is referred to as an altcoin.
The term "altcoin" might carry a negative connotation in Chinese, but its English counterpart is quite neutral: Alternative Coin, abbreviated as Altcoin. This means "alternative to Bitcoin." Bitcoin was the first cryptocurrency, and many subsequent projects imitated its codebase, tweaking certain parameters or adding new features. These were initially seen as copies or knock-offs, hence the name "altcoin."
However, as the crypto market evolved, many altcoins began to develop their own unique technological features and use cases, moving beyond mere imitation. From Ethereum (ETH)—the second-largest cryptocurrency—to functional DeFi tokens and community-driven meme coins, the altcoin landscape has become incredibly diverse, shedding its earlier image of simply following Bitcoin’s lead.
Altcoins can be categorized based on their function and purpose:
- Major Altcoins: Examples include Ethereum (ETH), Binance Coin (BNB), and Solana (SOL). These are large-cap cryptocurrencies ranked among the top by market capitalization, with robust ecosystems and active development communities.
- Utility Tokens: Such as AAVE and UNI, these are tied to specific decentralized finance (DeFi) protocols or application platforms. They are often used for governance voting or as incentive mechanisms.
- Stablecoins: Including Tether (USDT) and USD Coin (USDC), these are pegged to fiat currencies and are commonly used for payments or as safe-haven assets during market volatility.
- Meme Coins: Like Dogecoin (DOGE) and Shiba Inu (SHIB), these gain popularity through community support and viral trends. They are known for extreme price volatility.
- Scam Coins / Shitcoins: These lack technical substance, real-world utility, or even a whitepaper. They are typically created to defraud investors.
As of early 2025, there are tens of thousands of altcoins in the market, yet none have surpassed Bitcoin in terms of status or market cap. For beginners, understanding the types and risks associated with altcoins is essential knowledge in the crypto space.
How to Invest in Altcoins
What advantages do altcoins offer? As mentioned, their lower price points make them more accessible compared to Bitcoin. If you pick the right project, some altcoins can deliver returns of 10x or more. Early participants in new projects often benefit from airdrops and significant price appreciation—especially during the early days of DeFi or GameFi trends.
Moreover, many altcoins focus on innovative technologies, such as AI-driven tokens, restaking projects, or social tokens, offering opportunities beyond mainstream cryptocurrencies. Numerous altcoins were created to address Bitcoin’s limitations, offering improvements in transaction speed, lower fees, and smart contract functionality. Their applications are broad, spanning cross-border payments, on-chain gaming, and collateralized lending.
To purchase altcoins safely, it’s best to use major cryptocurrency exchanges like Binance, Coinbase, or Bybit. These platforms offer a wide selection of coins, better liquidity, and stronger security measures. In Taiwan, regulated exchanges like HOYA BIT and MaiCoin provide additional compliance safeguards. Avoid trading in unverified groups or with strangers to minimize the risk of fraud.
As cryptocurrency gains mainstream acceptance, many countries are approving crypto-related ETFs. In the U.S., there are already ETFs for Bitcoin and Ethereum, with several altcoin ETFs under review by the SEC. Currently, Taiwan has not approved any cryptocurrency ETFs, and even over-the-counter trading is limited to professional investors. For stock market investors who want exposure to altcoins without dealing with blockchain technology directly, purchasing related ETFs through international brokers can be a simpler and safer alternative.

Understanding the Risks of Altcoin Investments
While altcoins offer the potential for high returns, they also come with significant risks. With over ten thousand altcoins in existence, not all will succeed—much like how not every stock becomes a winner. Some are "shitcoins" with no real utility; others might be part of pump-and-dump schemes where developers abandon the project after luring in investors.
Even legitimate projects carry risks. Altcoins generally have smaller market caps and lower liquidity, making them highly sensitive to market sentiment. This can lead to extreme volatility, with prices sometimes halving or doubling in a single day. Additionally, many altcoins lack transparency, governance mechanisms, or regular financial reporting—making it difficult for newcomers to assess their true value.
Here’s how you can reduce your risk:
- Do Your Own Research (DYOR): Start by reading the project’s whitepaper, researching the team background, checking Total Value Locked (TVL) data, and reviewing development progress or update history.
- Manage Your Capital Wisely: Altcoins are high-risk assets. Allocate only a small portion of your portfolio to them.
- Choose Reputable Platforms: Trade through established exchanges and use trusted data aggregators like CoinMarketCap or CoinGecko to verify a coin’s legitimacy, trading volume, and community trust.
These steps help ensure you’re dealing with a genuine, widely recognized, and actively traded asset—not a fraudulent or low-liquidity token. Also, note that not all altcoins are listed on major exchanges. Smaller-cap coins may only be available on decentralized exchanges (DEXs), where low trading volumes can pose additional liquidity risks. Always proceed with caution.
Opting for well-established altcoins with larger market caps, conducting thorough research, and practicing sound risk management are more realistic—and safer—strategies than chasing after exponential gains.
What Is the Altcoin Season Index? A Tool to Time Your Entry
Wondering when might be a good time to invest more heavily in altcoins? One useful tool is the "Altcoin Season Index."
The logic behind this index is straightforward: it tracks the performance of the top 50 altcoins against Bitcoin over the past 90 days. It calculates how many of these altcoins have "outperformed" Bitcoin, providing insight into whether market momentum is shifting from major cryptocurrencies (especially Bitcoin) to altcoins.
The index ranges from 0 to 100. A value closer to 100 indicates that most altcoins are outperforming Bitcoin, suggesting that the market is in an "altcoin season." Conversely, a value near 0 signifies Bitcoin’s dominance, often referred to as "Bitcoin season." Values around 40–50 indicate a balanced or consolidating market without clear directional bias.
As of July 1, 2025, the Altcoin Season Index was around 20, reflecting a clear Bitcoin-dominated trend.
While this index helps capture the current market sentiment, it’s important to remember that it is based on historical price data—not a predictive tool. During broader market downturns, altcoins might appear "stronger" merely because they’re falling less than Bitcoin, not because they’re generating positive returns.
In short, the Altcoin Season Index serves as a helpful supplementary gauge for shifting market dynamics. If you’re considering altcoin investments, monitor this index alongside your capital allocation strategy and fundamental research. This approach is far more reliable than jumping in based on hype alone.
