Purchasing power of gold hasn't changed since 1971 - as per your chart .. That is what a true store of value is - is it not ?
I know you love #bitcoin .. me too ..
Steady gold means steady bitcoin .. because they are same ..
Some people (eg Mr Saylor :-) are trying to push a narrative that somehow gold can be demonetized .. that is a wrong notion - gold stayed steady even after fiat was unpegged in 1971- why ?
