Altcoin definition : what is it exactly?

In the wonderful world of cryptocurrencies, the Altcoin – Alternative coin – is a Bitcoin variant. In fact, the Bitcoin blockchain has been public, accessible, and open source since its launch. This has allowed many people to take its foundations to create other blockchains.

Today, many blockchains have emerged. All have different concepts, solutions to certain problems presented by the Bitcoin blockchain, mother of blockchains (speed of transactions, reduction of fees, etc.).

Altcoin definition

The notion of Altcoin encompasses all cryptocurrencies that are not Bitcoin. In short, there is Bitcoin on one side and thousands of Altcoins on the other.

What is the use of Altcoins ?

One may wonder the reason for the emergence of Altcoins. Why is Bitcoin not enough ?

By creating a currency running on a blockchain, Satoshi Nakamoto has created a monster of innovation. Only he created the first version of it.

Following this invention, many developers saw gigantic opportunities and wanted to evolve the idea.

Altcoins are therefore born from developers who want to create new innovations from the main innovation.

This is how today we find smart contracts, NFTs and all the web3 which is also developing.

Which promising Altcoins in 2023 ?

What are the most popular Atcoins in 2023, and why, where to buy them, how… But above all: what are the altcoins in which to invest… or not. Definition of the most famous tokens in a few lines.

Although we obviously cannot read the future or tell you which altcoin to invest in, here is a list of some cryptos to follow closely soon :

  • Ethereum
  • Ripple
  • Litecoin
  • Cardano
  • Sandbox token
  • Axie Infinity Token

Ethereum (ETH 2.0) : the altcoin without going through a third party

Ethereum (ETH) is a promising altcoin open to everyone : this digital token houses money, global payments and applications, giving up control of your personal data.

The Ethereum blockchain has brought the innovation of smart contracts. Ethereum can also develop other projects than digital money. Anything you own can be represented, traded and used as non-fungible tokens (NFTs) through this smart contract system.

The arrival of ETH 2.0 risks further revolutionizing the market since the Ethereum blockchain will improve, notably by moving from Proof of Work to Proof of Stake.

Ripple : the altcoin of banks

Altcoin Ripple is a real-time gross settlement (RTGS) system: an exchange market and remittance network built on a native digital currency called XRP (Ripple).

This promising Altcoin supports any fiat currency, cryptocurrency, or any other unit of value. Increasingly adopted by banks and payment networks, Ripple has a number of advantages: price and security.

Litecoin : the improved version of Bitcoin

Litecoin (LTC) is an enhanced Bitcoin cryptocurrency. Launched in 2011, cryptocurrency aims to become a real means of daily payment for its users.

This efficient altcoin erases some shortcomings of Bitcoin, including the slowness of the transaction validation process.

Cardano : the perfect synthesis

Developed by Charles Hoskinson, co-creator of Ethereum, Cardano is another promising Altcoin. Defined by some as the perfect synthesis of Bitcoin and Ethereum, this Altcoin allows the execution of smart contracts and also aims for carbon neutrality.

Cardano’s in-house cryptocurrency – ADA – now ranks third in capitalization : a good investment opportunity !

Sandbox token : the Metaverse explosion

SAND is the token of the well-known The Sandbox and is the explosive altcoin of 2022. If the metaverse phenomenon fascinates you, The Sandbox is the revolutionary project to invest in. Starting from a mobile game designed in 2011, the startup has grown to offer the most famous metaverse on the market today.

The Sandbox is a game that consists of a gigantic open world and uses the codes of Minecraft. This Play to Earn is already attracting very large investors who are buying virtual plots of land on the map.

The SAND token is therefore the native crypto of the game which is exchanged in the game and which allows players to buy objects, etc.

Axie Infinity token : a “play to earn” altcoin

The Altcoin Axie Infinity token is the native cryptocurrency of the Axie Infinity play to earn game built on the Ethereum blockchain. But making money raising virtual pets is not easy!

Play-to-Earn game markets are tricky: the three main cryptocurrencies in the ecosystem (AXS, SLP and RON) have lost a lot of value in recent months.

How to store Altcoins ?

To best store your dear Altcoins, you will use wallets : programs also called “wallets” which develop a process for storing digital coins via private keys which protect access to them. Wallets – or purses – are therefore in reality key rings…

However, the platforms mentioned above do not require the opening of an external wallet and they offer one within their solution (also called custodial wallet). External wallets are used to connect to decentralized finance protocols or to store cryptos on a fully decentralized wallet.

Interfaces between the real world and cryptocurrency protocols, many wallets exist on the market. Difficult to make a choice, but we can already separate all the wallets into 2 distinct categories : hot wallets and cold wallets :

  • hot wallet will be directly connected to the Internet when in use. These are also hosted on the Internet and are a kind of software. Most hot wallets are browser wallets which are in fact extensions to install on your browser
  • cold wallet will not be and will provide maximum security by reducing the hacker’s attack surface. Keeping large amounts of Altcoins with a cold wallet is therefore strongly recommended. These are comparable to USB sticks or external hard drives
