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.

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.
