Gold is scarce but it has no limited supply. Bitcoin has limited supply.
Gold is not easy to save. Bitcoin is easy to save if you read and understand about it.
That is true. When the price of gold goes up, it incentives people to mine more of it and the supply goes up.
But more bitcoin can't be created no matter how great the demand and price is rising.
There is a hard limit how much an be mined each day, and it is cut in half every four years.
So the bitcoin supply is not only capped but also shrinking.
OTOH as the price of bitcoin goes up the supply of altcoins printed out of thin air also goes up by the billions
if not trillions. The amount is unlimited. Shitcoins are a replication of the fiat system only ten times worse.
