I completely disagree with your statement. Bitcoin consumes that energy undeniable, but to say that bitcoin mining worsens the environment is not true. The amount of energy used to mine bitcoin is nothing compared to the energy consumption of other industries. Moreover, bitcoin is creating value and benefits for us, and society, so it is completely appropriate to consume energy. We live in a world of technology, and energy use is happening in all our activities, even at our dinner table, so would you call it a waste?
