- vasilipupkin 8y agogold mining uses a ton of energy, more than bitcoin mining. To the extent that people substitute gold for bitcoin in financial portfolios, this is positive since net energy waste is lower.
- moocow01 8y agoHow do you know that gold mining uses more energy than bitcoin mining?
- vasilipupkin 8y agoI mean, I don't know it for sure, that's why I said "to the extent..." but here is one article https://www.bloomberg.com/view/articles/2017-12-07/bitcoin-is-greener-than-its-critics-think https://www.bloomberg.com/view/articles/2017-12-07/bitcoin-i...
- JBReefer 8y agoGonna need a lot of citations to believe that

- mikeash 8y agoIt seems like a bad comparison, since you don’t need to mine gold just to move it around. Transferring ownership can be accomplished for the amount of energy it takes to send a small electronic message.
- vasilipupkin 8y agoto move it around you need trucks which use gasoline
- mikeash 8y agoYou don’t need to move it to transfer ownership of it.
- vasilipupkin 8y agoby that logic, same thing applies to bitcoin. on a centralized exchange ownershp is just an entry in the database
- mikeash 8y agoIt would apply to bitcoin if that were the usual way to transfer it, but it doesn’t look like that’s the case.
- vasilipupkin 8y agowhat do you mean? most bitcoin volume is done on centralized exchanges, so that's exactly the usual way of trading it.
- mikeash 8y agoFrom some quick searching around, volume on the exchanges is around 500,000/day while volume on the blockchain is over a million. If that’s accurate (and it may not be, I’m not an expert on this and the sources I found might suck) then most volume is on the blockchain by a pretty good margin. I don’t know how much gold is actually shifted around physically, but the trading volume in a year is several times the actual amount of gold that has been mined, so I suspect the proportion of that which involves physical movement is tiny.
