Here is an interesting quote from a famous film about digital currencies and government securities, "... it is unconstitutional, you can not create its own currency. It is the job of the Federal Government! We can not allow you to make loans in Z-Coyne, you would not be able to issue in dollars. " And now judge for yourself that will live, Fiat or bitcoin.
The value of your money is determined by the global casino of unprecedented proportions: every day two trillion $ US trading on the foreign exchange markets - ie 100 times more than the trading volume of all stock markets in the world combined...
Only 2% of foreign exchange transactions is relevant to the "real" economy, reflects the movement of real goods and services in the world, while the remaining 98% - a purely speculative.
You can't directly compare these two figures
Just like you can't compare grams with meters (or pounds with yards). If someone traded one dollar one million times, that would amount to 1M dollars of trading volume. Could we then compare that value to someone else selling something real for the same quantity of dollars? I guess this seemingly excessive amount of trading volume is required to get a correct estimation of the exchange rate but apart from that, it is mainly inconsequential to real economy and trades that involve exchange of real goods
