Top 10 Most Sustainable Cryptocurrencies to Invest in 2023

Sustainability in the crypto sector is more concerning as climate change affects the planet and people’s health more every year. But the trend of green cryptocurrencies started after some light was shed on the considerable environmental impact of Bitcoin, the first digital coin created in 2009. With enormous carbon footprint statistics, the coin’s efficiency and reliability were overshadowed by its negative effect on the environment. Therefore, many investors looked for green alternatives, or at least cryptocurrencies making an effort towards sustainability.

Ethereum, for example, made an impressive step towards better practices by switching from the old PoW to PoS, eliminating 99.99% of its carbon footprint. On the other hand, newer cryptocurrencies already promote themselves as green since their arrival on the market, targeting a specific customer audience. But what makes a cryptocurrency sustainable? It’s not reducing a coin’s or blockchain’s energy consumption but also includes alternatives for keeping the network efficient and scalable. Carbon offsets are also popular solutions.

Sustainable cryptocurrencies are essential for environmental safety but also make investors aware of their impact with more and more people following day trading signals the trend is always rising year on year. Technology and development can’t continue affecting the environment when their purpose is to improve people’s lives.

So, here are the top 10 sustainable cryptocurrencies you might want to invest in 2023.
