Are you seriously? In order to "return" to gold and start trading it, you must have considerable reserves of funds. In simple language, you should be rich in order to allow yourself to trade in gold. This is the advantage of cryptocurrency, everyone can start working.
You didn't even read the discussion. Who talked about trading Gold? Gold is a store of value, not really an asset to trade with. People buy Gold not to make a profit but rather to secure their funds. To secure from inflation, government, banks, etc.. You guys can't even understand simple things.
Even a 10 years old kid do it, but not you!
Just the same people with very good finances can only afford. Ordinary mortals do not care about gold. A cryptocurrency is their chance to become something more.
