The biggest threat to fiat money is inflation. Inflation can be cured by injecting wealth into the economy and by that rising enough belief to keep the system afloat. This can be done for instance by occupying foreign countries and by that opening up new markets to the companies that are essential to the economy. Or this can be done by loose regulations with the derivatives markets, that will create wealth out of thin air and high hopes.
Can it be that pumping of the crypto markets is just another financial shenanigan created to keep the old system afloat?
They are creating new wealth out of nothing with cryptos, just like with derivatives. The made up wealth that is created, is actually backing the value of fiat. This would make sense why regulators seem so blind on goxdollars and tether.
I dont know for sure, but it might be true. If inflation is taking place, it doesnt happen in everywhere, just some places. It might be that Bitcoin was made to support fiat currency, but we are not really sure of that, cause based on the introduction it doesnt state that Bitcoin was meant for such purpose, there are other purposes in which it was made than that. And also, some people seems to be misunderstanding Bitcoin and they believe that the reason it was made is to replace fiat.
