Any industry or sector that consumes energy will produce emissions, and bitcoin mining is no exception. But the problem here is that the climate change impact from bitcoin mining is negligible compared to many other sectors, but many people are over-exaggerating it and cause unnecessary misunderstandings.
Bitcoin is also a field that is bringing benefits like many other industries and the benefits it brings to us are even greater so consuming energy or creating emissions is acceptable.
Whether we have bitcoin or not, climate change will still happen, don't just blame bitcoin or any other field, instead it is us humans who are destroying this earth.
