So. Is the dollar.
In fact the dollar may be more like air in a balloon than Bitcoin.
Bingo.
Perhaps, but the dollar is still the strongest fiat currency in the world. Bitcoins aren’t worth two bits compared to the dollar. Bitcoins will lose most of its value overnight. Possibly 100%. The dollar might lose 10% of its purchasing value in the course of a year. That was as bad as it has ever gotten. That was during Carter.
Bitcoins are not only a fiat currency. But they can be summarily declared illegal by any government tomorrow. Then all you will be holding is a computer filled with worthless electrons.
Invest at your peril.
