What is Altcoin: The Complete Guide for Alternative Cryptocurrency Investors

Entering the World of Altcoins

While Bitcoin remains the leader in the cryptocurrency market, the economics of altcoins are growing at an unprecedented rate, like a runaway train. Since the launch of Litecoin in 2011, the number of alternative cryptocurrencies has increased to over 16,500, each with its own specific purpose and unique value proposition.

Currently, altcoins account for approximately 55% of the total cryptocurrency market capitalization, indicating that investors are not only focusing on Bitcoin. They are exploring new innovations and opportunities offered by altcoins.

What is an Altcoin? Basic Meaning

The term “altcoin” comes from combining “alternative” and “coin,” referring to any digital currency other than Bitcoin. This classification is simple but has significant implications.

Coins, Tokens, and Differences

Coins operate on their own blockchain and are the native assets of the network, with Bitcoin and Ethereum being prominent examples.

Tokens are another matter – they operate on other blockchain platforms, such as Ethereum, which serves as the infrastructure for many tokens created on its network. They serve various functions but do not have their own blockchain.

Most altcoins are created to overcome Bitcoin’s limitations, whether it’s slow transaction speeds, high energy consumption, or lack of flexibility in applications.

Classification of Altcoins: Market Diversity

The altcoin market is slightly less diverse than Bitcoin but still clearly divided into several categories.

Stablecoins: These digital currencies are pegged to real assets like USD. Examples include USDT and USDC, making them popular choices for traders seeking to avoid volatility.

Utility Tokens: These provide access to services within a network, such as XRP and SOL.

Governance Tokens: Holders have voting rights in project decisions—think of them as shares in a company.

Security Tokens: Represent ownership in external assets like stocks or real estate.

Meme Coins: DOGE and SHIB started as jokes but gained a loyal community.

Play-to-Earn Tokens: Blockchain-based gaming projects that reward players with digital currencies.
