You have compared btc with physical gold.
How about comparing btc with a gold-backed stablecoin?
Why? Who cares?
For example, if you compare the transaction speed of Bitcoin vs. Gold, it doesn't make any sense to compare Bitcoin with a piece of rock.
Gold ownership can be traded physically (as a piece of rock) or digital (as a stablecoin)
It only make sense to compare digital (Bitcoin) with digital (gold-backed Stablecoin)
