Mining cryptocurrencies is intensely energy consuming. The use of energy intensive computers keeps creating problems for the miners as it has adverse effects on the environment and also pokes their finances in terms of high electricity bills.
Is it the most energy consuming?
Let's be honest, there are probably so many things in the world that consume way more power than crypto mining but guess what? You are always going to blame miming crypto for all that.
I haven't seen people make noise about how watching TV or using electric ovens to cook can impact the environment, for example.
Crypto halvings could also accelerate green energy adoption among miners.
You mean these "green energies" that use batteries that need the extraction of raw materials which process leads to the destruction of the environment somewhere deep in a Third World country, like this?
Let someone convince me how the process of attaining the raw materials for the manufacture of Lithium somewhere deep in the Democratic Republic of Congo is Environmental friendly.
