In this review paper we provide an overview and synthesis of recent literature published in the last two years that addresses the sustainability of bitcoin. Bitcoin may pose risks to the stability of the current financial system, while also lack of controls over bitcoin exchanges and the volatility of the bitcoin currency raises concerns. The contributions of this paper are: firstly, to synthesize and critically assess the viewpoints in scientific literature; and finally, to argue that the energy consumption of the bitcoin system is not excessive, which stands in contrast to the public opinion that bitcoin
mining is a gross waste of energy. In the following sections we outline the basic operation of the bitcoin system, we summarize trends in the hardware used for bitcoin mining, we discuss the energy footprint of bitcoin
mining, we present some of the alternatives that have been proposed to reduce energy consumption, and we briefly discuss other applications of the blockchain technology that is at the basis of the bitcoin system. We try to answer the question whether the bitcoin system is sustainable given the energy consumption required for bitcoin mining, which has been subject of debate in the last few years. Our focus in this review is on sustainability in the context of environmental and economical aspects. We explore four subquestions: What factors play a role in the energy consumption of bitcoin mining, how large is this energy consumption, does this impede sustainability, and if so are there alternatives that can reduce energy consumption? The sustainability of bitcoin is depending on a mix of environmental [10••, 11••], economical [1, 12], financial [2, 13, 14] and ethical  aspects.
