40% of gold consumed is in investments, 50% in jewelry, and 10% in industry, so I'm not totally sure how it works out in terms of energy per unit of gold, but it's likely some mining of gold would be necessary even if you stopped using gold for jewelry and investing. But you could get rid of bitcoin (and other crypto currencies) without any real impact.
perhaps. you could get rid of most of things in our society without much impact, since we basically need food, water and shelter. but lots of things are nice to have, so that's kinda irrelevant
I think cryptocurrencies have very few practical applications at the moment. So getting rid of them would have much less effect than getting rid of gold for example.
yes, that's because they are 10 years old as opposed to 10,000, but I am not sure where you are going with this. At the very minimum, getting rid of them would cause investor losses of hundreds of billions.
gold 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.
It 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.
From 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.

to the extent it's taking away from mining gold, it's a positive thing

I don’t follow. Can you explain?

to move it around you need trucks which use gasoline
You don’t need to move it to transfer ownership of it.
by that logic, same thing applies to bitcoin. on a centralized exchange ownershp is just an entry in the database
It would apply to bitcoin if that were the usual way to transfer it, but it doesn’t look like that’s the case.
what do you mean? most bitcoin volume is done on centralized exchanges, so that's exactly the usual way of trading it.

https://blockchain.info/stats
total USD transaction volume according to above about $1.3bln
trading volume, according to https://coinmarketcap.com/ - 6.7 bln
most bitcoin volume is virtual, not generating actual transactions, by 5 to 1 margin. Not sure where you got your numbers
What is the difference between “Total Output Volume” and “Estimated Transaction Volume”? The former is pretty close to what I found.
How do you know that gold mining uses more energy than bitcoin mining?
I mean, I don't know it for sure, that's why I said "to the extent..." but here is one article

Gonna need a lot of citations to believe that
