Do you think this is a good idea?
I have seen that kind of project that they are for a greener environment but I don't know where the majority if not all of them.
Will big blockchain companies start using these eco-friendly methods, and how will this change the industry?
As I've said, most that I have seen aren't remembered today and if a project wants to make the environment greener, it won't be with blockchain technology but with methods like recycling, segregation of waste, planting of trees and etc. Not with a blockchain project that only wants to garner fund for their tokens.
