It may be a bubble, but it is going to be the strongest bubble no one can easily burst it. Fiat money is intrinsically nothing. But it has become everything because it has the sanction of the government. It is fully backed up with clear stipulations in constitutions. It has the approval and agreement of domestic and international companies big and small, and generally everyone. That is enough to make it very precious so much so that it has become life itself to many.
