What Is an Altcoin?

An altcoin is an alternative (alt) coin. In other words, it is any currency other than Bitcoin if you want to invest in cryptocurrency. Indeed, Bitcoin is considered the number 1 cryptocurrency and, above all, the reference digital currency. Altcoins are now extremely numerous, and investors are free to put their money into the projects that match their expectations.

How to Research Altcoins: Key Characteristics

A Blockchain for the Altcoin – Cryptocurrencies always live inside a chain of blocks. Indeed, a block generally builds on the block before it, which is where the name blockchain comes from. A new block therefore gives rise to another new block. This whole set of interconnected blocks is open to all users and investors. It is therefore recommended, in order to make gains, to buy cryptocurrency, but you must pay attention to the risks.
Altcoin Cryptography – Cryptography is another concept that comes up when virtual currency projects are discussed. The term refers to the complete encryption of transactions, which makes them secure and tamper-proof. The techniques employed by the blockchain secure transactions and make them unbreakable. As an example, Bitcoin is based on SHA-256 and Ethereum uses Ethash.
The Token That Materializes the Altcoin – Tokens represent assets that are inherent to and important for a blockchain. Acquiring a Bitcoin therefore amounts to buying a token. Moreover, tokens have a value and a market price, which makes it possible to know the price of cryptocurrencies in fiat currency.

Ethereum (ETH)

Ethereum is the main altcoin rival to Bitcoin. It is a cryptocurrency created in July 2015 by Vitalik Buterin. Centered on smart contracts, it is one of the most popular digital currencies, with a blockchain used by many other altcoins. This currency not only makes it possible to verify data, but also offers smart contracts through Turing completeness.

Just like Bitcoin, Ethereum can be acquired through the mining process. While some cryptocurrencies are based on fake projects, Ethereum, by contrast, is a currency of real utility on the market. Since its creation, it has remained a useful currency and is expected to deliver even greater performance over the long term. It is also worth remembering that it is possible to buy Ethereum with PayPal if you want to acquire some.

Ripple (XRP)

Ripple is an open-source indexed altcoin that boasts one of the largest market caps in the world, with 19 billion euros worth of tokens. It was created in 2011, well before Ethereum, by issuers Arthur Britto, David Schwartz and Ryan Fugger.

Litecoin (LTC)

Litecoin is a digital currency created in 2011 with a very small number of final blocks. Like Ripple, it remains one of the most historic digital currencies. It was founded by Charles Lee and holds one of the largest market caps among virtual currencies worldwide.

Cardano came to life in 2017 through the co-founder of Ethereum, Hoskinson. On the technical side, Cardano remains a centralized project under MIT and Apache licenses. For this reason, it makes sense to buy Cardano in 2026. Mining is possible with the Cardano currency.

In the same vein as Ethereum, Cardano is recognized as an open-source crypto project. Investing in this currency matters because it remains one of the trendiest cryptos built on PoS and one that received strong backing from Bloomberg, which allowed it to break through on the world stage.
