As we know, for bitcoin mining lots of electricity required, so if this way we continue doing,Is it affect the environment ?
Lots of electricity means lots of coal burned.
So shall we go towards green energy ?
I kind of see what you are getting at... and I agree.
There is no way that crypto will be allowed to consume so much electricity.
There will eventually be a world wide consortium introduced to ensure that:
1) Crypto is only mined using clean energy
2) Crypto is taxed to offset its carbon footprint
