244,000 metric tons of gold has been discovered to date, 55,000 tons of gold are left.
But there is still a lot of gold left in the universe. There is gold on asteroids for example. One day these will be minable. So the gold supply is not as limited as some may think.
However, gold is hard to move around, weighs a lot, it's hard to sell or buy, it's not practicable.
With BTC it's another story. We all know there are only 21,000,000 coins and 3-4 millions are already lost forever.
There is no Bitcoin in the whole Universe, except on Planet Earth.
BTC is scarcer than gold. I think one day 1 BTC will enter the $xxx,xxx zone then the $x,xxx,xxx HODL BTC
I don't really think only the scarcity of something decides the price of an asset, it's always the combination of Demand and scarcity that decides the price, due to this traditional mentality gold has always fetched a hell lot of demand and even though there has been a lot of production still the price has gone up in a linear manner. If bitcoin in the same manner continues to attract demand from retail investors it will obviously keep rising in price but if the demand get's killed due to failure of bitcoin as an utility then obviously it won't attract that much demand and eventually the price movement wouldn't really be that much.
