Wow. Where to start on this one!

Where do you see the problem in using less energy for a crypto currency? Why not make a cryptocurrency that uses even more energy?

[artifact_44]

Because electricity costs money. When the cost of electricity exceeds the value of coin you mine, you will stop mining. If you make a coin that takes half as much energy to mine, miners will just mine twice as much of it. Its like y'all are just discovering capitalism for the first time.

those currencies already exist. people can choose to use them, while understanding the trade-offs.
