Digital fiat. Why buy bitcoin when you can buy gold and silver instead.
Because 95% of dollars exist electronically, because online transactions dominate the world over. Gold and silver will always have some value, but the idea that you are going to be buying things on Amazon or paying your utility bills someday with chunks of shiny metal is silly. Government fiat is fatally flawed as politicians invariably favor deficit spending until they destroy their national currency. Every day that passes with the US government wildly outspending its revenue leads to the debt snowballing as interest rates stay high.
When the dollar/yen/euro etc. collapse as they very obviously will, we won't be going back to the stone age and transacting in precious metals. Nor will anyone sensible shift to the next round of government-issued, non-scarce currency. Bitcoin and its competition will of necessity be the global replacement people turn to.
I buy bitcoin, Litecoin, and 3 other alt coins, as well as physical silver and gold. I also have invested more this year in the stock market than ever before and am up for the year 19%,
