Do you know the primary reason why the gold standard was almost universally abandoned? The same flaw behind gold standard failure will inexorably plague Bitcoin in the end, if it ever happens to get into mainstream...
Everyone blamed the Wall Street Crash of 1929 and the subsequent economic depression of the 1930s on the gold standard, and that was the main reason why it was abandoned. But I am still a strong supporter of the gold standard, and I believe that the abandoning of it is the main reason for hyperinflation, which is prevalent in many of the world nations.
