The topic of the consumption of a large amount of energy by bitcoin, as well as its consumption of carbohydrate sources, has been raised and is unlikely to disappear on its own. Now this is very important in connection with the sharp climate change, and therefore the states will gladly pick up this topic in order to criticize Bitcoin. Bitcoin really needs to do something to consume less energy, otherwise it will soon lose interest from institutional investors. In this regard, ethereum now compares favorably with bitcoin, the network of which, when updated, will dramatically reduce energy consumption. Therefore, it is predicted that ethereum can bypass bitcoin in terms of price dominance and capitalization.
