Gold is not backed by any asset like Bitcoin, nor by any fiat currency.  It makes me wonder if I should invest/trade in gold or not?

Fiat currency is not backed by any physical asset like Gold or Bitcoin. It makes me wonder if I should invest/trade in fiat or not?

Bitcoin doesn't need to be "backed" by anything. It is an asset. It has use. It has value. It has demand. It has supply.
