Cryptocurrencies and their impact on global warming.

Nowadays, cryptocurrencies have gained a wide ground in reference to traditional physical currencies, this is due to the great economic growth that they are generating in the world, for example, the cryptocurrency that has grown the most is the BitCoin, which multiplied by ten its value in the medium term, which has increased the interest in this cryptocurrency. Although it may seem untrue, BitCoin is a great consumer of energy as the rest of the cryptocurrencies that work under the blockchain technology, since this technology requires the connection at the same time of hundreds of computers worldwide that make the blockchain can operate through its Nodes, this massive energy consumption directly affects global warming. Currently the environmental challenge has become a major concern in the blockchain world in general, according to Joseph Pallant founder of the Blockchain of Climate states that "It is a big deal to calculate the carbon footprint of these digital instruments", remembering that it is a fairly polluting technology. A comparison that can be made to know how big is the impact that cryptocurrencies are generating to the environment is when measuring the carbon footprint of these, especially that of BitCoin which is very similar to that generated by the economy of Ireland, which produces about 39 megatons of CO2 released into the atmosphere each year. Similarly, a research conducted by the University of Hawaii revealed that if the use of cryptocurrencies continues its accelerated growth, the Earth's temperature could increase by 2 degrees in less than two years. In conclusion, if cryptocurrencies are here to stay and revolutionize the financial world, it is necessary that they can migrate to clean energies in order to reduce their impact on the environment and create an Eco-Financial balance that allows a better development of the economies of the countries.
