@TEAMSWITCHER do you realize USA prints money, despite they gold reserves are long gone
Everyone prints money. Why? Because attaching the value of your currency to gold (or any other commodity) is just a bad idea. This is one of the few things nearly all economists agree on.
The big difference between countries like the USA and countries with hyperinflation is the US has an independent central bank. Doing away with the Federal Reserve would hand control of the currency directly to politicians, which is a sure recipe for economic chaos. Bringing back the gold standard wouldn't fix this.
As for crypto currencies, there are basically two ways to use them. You can use them as an investment, hoping they'll appreciate in value. Bitcoin is good for this (unless it crashes), since the supply is finite. The other way is to use them purely for transactions, for which Ethereum is better. In the second case, as long as you don't hold the crypto currency for long term, there's little risk.
The thing that bothers me about blockchain is that I don't see how it can economically reach large enough scale to be practical for any significant fraction of transactions. Ethereum might be fine for real estate transactions, but we won't be using it to buy a pack of gum.
