gold is an unregulated comodity too ... so could the BTC be in a different form ... hence neither have anything to go by except for their scarcity value - Economics Alumni

On the other hand I think it would be safe to assume that current fiat inflation brings about an upward trend for bullion in general; that being said, we often forget that the rate of appreciation a particular thing is not a function of economics !!!! Supply and demand is only an effect and not a cause ... Everyone should get the fact that Kensian economics is dead ... Welcome to the new world of causing such effects - try mass manipulation and perception alteration. ( that's another subject altogether )
My previous point is that we got an inflationary coin like the fiat, a relative stable quantity of gold and a deflationary wannabe.
If you want, that could be your thesis / final dissertation ...
Take care and good luck !
