Unsure about this, but you can imagine how a limited supply of oil gonna affect the price of the oil, imagine that oil gonna dry up next year, price will greatly increase for the time being until someone come up with a new idea to replace it, that what will happen to bitcoin too if there is a demand and usagebility to it
for now, bitcoin seem to be irreplacable because of its unique feature, anyway bitcoin hasnt achieved its main goal by now, i believe satoshi created this to become decentralized currency, which we know by now, only a fraction of the population even know about bitcoin
