bitcoin has a controlled amount , there could be a million kg of gold undiscovered.
Not really.the gold resources that were not mined yet, are already identified and are scarce as well (that is why gold is one of the precious metals).
Also the ore quality is decreasing, so it costs more to get the same amount of gold.
Not really.
Asteroid mining is now within the realms of becoming viable. The gold resources there will dwarf anything seen on this planet. Once the transport mechanisms have been developed for recovery the gold is imminently more accessible, i.e. it is basically there in a pure form waiting to be "picked up".
Asteroid-mining pops up from time to time as a "game-changer" in the press, but the fact is for now there is nothing mature enough to affect the price of gold.
We may use this as an argument once this becomes a real possibility, for now it is a bit off-topic, I am afraid.
Point being, you said gold was scarce and this is incorrect. More correctly it is technically inaccessible, for now.
Viable means economic to retrieve in this context, if that was not obvious. There is now an identifiable technology development path towards retrieving gold from asteroids, do your own research on this if you do not believe me, I don't have time to lay it all out for you. Time and costs to becoming viable will only decrease from here onwards.
Ever since the Philae Lander, one cannot doubt any of these claims.
