Bitcoin has a limited amount and will not change over time -> Same as gold.
I don't quite agree with this, Bitcoin has limited supply true, but can never be the same as Gold considering that we cannot accurately estimate the amount/quantity of undiscovered gold in the planet. You know just recently a huge deposit of gold was discovered in Uganda,
Recent exploration surveys in Uganda have led to the discovery of approximately 31 million tons of gold ore deposits
source This recent deposit discovered alone is more than the total fixed amount of bitcoin that can be mined. This discovery of this large amount of gold makes one wonder and accept the possibility that there can also be another deposit of gold as large as that sitting somewhere undiscovered.
