Both gold, fiat and bitcoin as a medium of exchange or as a currency depending on the use of each individual.
For me, gold is no longer used as a currency after Fiat is an agreed payment tool. Gold has become an asset that is stored because of its different values ​​from Fiat which continues to decrease due to inflation.

The presence of Bitcoin is the best alternative. Yes. Bitcoin as a currency that can be used as a means of payment very easily can also be used as a long -term investment asset. Slowly, intelligent thinkers have begun to recognize that Bitcoin is better as an alternative currency because the system is transparent and even becomes an asset that can be expected in the future.

However, the interested parties continue to argue that Bitcoin is far worse because it can be used for bad actions.
