What about the problem that mining operations are using tremendous amounts of energy and therefore putting huge amounts of carbon into the atmosphere? As bitcoin grows and gets more valuable, doesn't that mean more miners and therefore, more carbon? What is the solution to all this?
If you are doing a mining operation off-grid that is solely from solar, then perhaps you will be part of a solution. But in general, here's a detailed analysis that looks at the energy issue and it's pretty damning of Bitcoin and PoW crypto. https://www.ofnumbers.com/2021/02/14/bitcoin-and-other-pow-coins-are-an-esg-nightmare/ A key quote: "If you are an asset manager considering whether or not to include proof-of-work coins in your portfolio – and have an ESG mandate – or a policymaker considering whether or not to encourage the proliferation of these types of coins in your jurisdiction, it is pretty clear that PoW coins such as Bitcoin are an ESG nightmare and not a suitable fit. If and when some (or all) of these coins transition to proof-of-stake is beyond the scope of this article."
