Comprehensive Guide to Environmentally Friendly Cryptocurrencies

Cryptocurrencies are often lauded as a revolutionary shift in how we think about finance. They offer decentralization, low transaction fees, and financial inclusivity. However, given the complexity of mining new coins and conducting transactions on an ever-growing network, there’s a concern surrounding the environmental impact of cryptocurrencies.

Because of that, countless crypto and environmental enthusiasts alike are looking to add “green” cryptocurrencies on their CEX.IO BTC wallets.

This guide aims to unpack this complex topic and highlight environmentally-friendly cryptocurrencies you can invest in. Ready to level up your crypto game while staying green? Let’s dive right in.

The Basics of Cryptocurrency

Cryptocurrency is digital money, or an asset, that uses cryptography for enhanced security. But unlike conventional currencies, cryptocurrencies don’t come in physical form and aren’t controlled by central authority, such as a government or a bank.

Instead, people can buy, sell, hold and trade crypto seamlessly using desktop or iOS digital wallets by registering with trusted crypto exchanges. In the lines that follow, we’ll focus on environmental-friendly cryptocurrencies and their potential to disrupt the existing crypto market.

How Cryptocurrencies are Mined

“Mining” might evoke images of digging into the earth, but in the crypto world, it’s a digital process where transactions are verified and added to the blockchain. Miners use high-powered computers to solve complex mathematical problems.

Upon resolution of these issues, they can authenticate transactions added to the blockchain. This procedure consumes significant amounts of electricity, particularly in the case of currencies such as Bitcoin.

The Energy Consumption Issue

Imagine your household electricity consumption. Now, imagine it multiplied millions of times. That’s how much energy some cryptocurrency networks consume.  Bitcoin’s energy consumption rivals that of small nations, and that’s just one cryptocurrency.

Why Should We Care?

Climate change isn’t a distant issue; it’s happening right now. Every industry needs to assess its environmental impact; crypto is no exception.

Importance of Environmental Sustainability

It’s high time we prioritize environmental sustainability. Our planet’s resources are finite, and irresponsible practices today could lead to a depleted Earth for future generations. Energy-intensive mining contributes to global warming and climate change, creating urgency for sustainable alternatives.

The Ripple Effect of Energy-Intensive Mining

Energy-intensive mining has a broader impact than just electricity consumption. It contributes to the global demand for fossil fuels, driving up prices and affecting entire economies. It also has a social impact, contributing to resource scarcity in areas with limited energy resources.

Traditional vs Environmentally Friendly Cryptocurrencies

Traditional cryptocurrencies like Bitcoin use a Proof of Work (PoW) system for transaction verification. While effective, it could be more efficient regarding energy consumption.

Features of Traditional Cryptocurrencies

Traditional cryptocurrencies rely heavily on computational power, leading to high energy consumption. This is especially true for Bitcoin, the largest and most well-known cryptocurrency[2] 

What Makes a Cryptocurrency Environmentally Friendly?

Environmentally friendly or “green” cryptocurrencies aim to solve this issue by adopting energy-efficient protocols. For example, they may use Proof of Stake (PoS), a more efficient alternative to PoW, or even other innovative solutions like sharding or layer two.

PoW vs PoS: The Protocols that Matter

Understanding PoW

In a PoW system, miners compete against each other to solve mathematical problems. The first to solve the pain gets the possibility to add a new block to the blockchain and is rewarded with some cryptocurrency. This method, while secure, requires a lot of computational work, hence energy.

Why PoS is Considered More Eco-friendly

PoS offers a different approach. Instead of miners competing against each other, the network choses one, or more, to create new blocks. This is done based on the number of coins (tokens) they hold and are willing to “stake” as collateral. This system drastically reduces the energy required for the mining process.

Key Players in Eco-Friendly Cryptocurrencies

Ethereum 2.0

Ethereum, the second-largest cryptocurrency by market cap, just behind Bitcoin, has switched from a PoW to a PoS system. This transition, Ethereum 2.0, is a massive step toward making the crypto world more sustainable.


Cardano was designed to be eco-friendly from the ground up. It has used a PoS system since its inception, making it far more energy-efficient than its PoW counterparts.


Nano is a lesser-known but up-and-coming green cryptocurrency. It uses a unique block-lattice architecture, removing the need for miners altogether. This dramatically reduces its energy consumption.

Where to Buy Environmentally Friendly Cryptocurrencies

Investing in green cryptocurrencies is more than just a financial decision; it’s an ethical choice. With the growing awareness around the need for environmental sustainability, more platforms are beginning to offer eco-friendly cryptocurrency options. Here are some places to get your hands on these green assets.


Coinbase is one of the most popular cryptocurrency exchanges. It’s known for its user-friendly interface and diverse range of cryptocurrencies, Coinbase has also started to list more eco-friendly options like Cardano. They offer a secure and easy way to start your green crypto journey.


Another heavyweight in the crypto world, Kraken offers a robust platform for trading various cryptocurrencies. They’ve also included environmentally friendly options, making it easier for traders to make eco-conscious decisions.


An exchange that’s gained trust and a large user base over the years is CEX.IO. They offer a wide range of assets and services for those who want to invest in green cryptocurrencies. The interface is user-friendly, and their security measures are top-notch.


Binance is a giant when it comes to cryptocurrency exchanges, boasting an immense variety of cryptocurrencies. They’re beginning to include more green options like Ethereum 2.0, providing users with more environmentally sustainable alternatives.


Green or environmentally friendly cryptocurrencies are poised to become crucial to the financial landscape, providing a sustainable alternative to traditional, energy-intensive cryptocurrencies.

As investors, it’s our responsibility to support technologies that are not just financially promising but also sustainable for our planet. With increasing adoption, government regulations, and technological innovations, green cryptocurrencies are not just a fleeting trend; they are the future. So, are you ready to make a wise, sustainable investment?

i’d rather cut this because it’s not explained how many cryptocurrencies can be mined with this energy or for how long can bitcoin network run consuming this energy

i don’t see how these two sentences connected when the first one is about traditional currency and the second about crypto

this is a pure financial advice, please rephrase
