It's good that you pointed out that the ETF demand for Gold was because of demand for gold in the early 2000's. At that time commodities were booming due to low interest rates and a weakening dollar...inversely raising the value of gold.
You are correct that 2008 and the money printing by the Fed increased the value and demand for Gold.
Which leads you to a good conclusion that if investors have high demand for a traditional finance vehicle to invest directly in Bitcoin, that the price will also rise. It's great that they are also bitcoin settled so people will get a ownership stake in Bitcoin, like you say. This might be a great catalyst for getting big, institutional money into crypto! Crypto up to this point has been mainly retail investors and hedge funds with a large risk appetite.

Yes good point. The first fomo rally was lead by retail, the next one will be lead by institutions. :)
