If anyone can give me an annual estimate of the energy wasted in minting coins, through mineral mining smelting forging etc; in printing currency, including the harvesting or resources for ink and material, then I'd be happy to address the current cost of energy that crypto creates.
There are 180 currencies in the world today. Each and every one mints coins, prints "paper" (or plastic), currencies and spends a lot of energy on it.
Before we start going on about the cost of crypto, we also have to assess the ongoing cost of crypto as opposed to the ongoing cost of physical cash. Crypto, once mined, is zero cost. Physical currency must be refreshed on a regular basis. Incurring not only production costs but secure decommissioning costs too.
Once we understand the true cost of traditional currency, then it will be possible to weigh the costs and benefits (if any), of crypto.
