You can't move, sell, verify or store physical gold without a huge amount of hassle.
There's no point making this comparison.
They stuck a paper market on top of gold as otherwise there basically isn't one.
That's not the case with bitcoin.
Dude, CME and CBOE are implementing the exact same methodology as gold futures. The paper contracts are settled in cash. Next to no BTC is involved. Its a moot point.
Of course you could not make direct comparison with gold. Gold's immovable and expensive to store property indeed makes it different from BTC. because it means for example, it will cost you approx 1% to hold gold but holding real BTC is not as nearly as expensive.
BTC's easy to move nature also means any anomalies in the futures market could also easily be arbitraged away.
