In 2018 Robert Kiyosaki classified money in 3 parts saying we have Fiat, Digital and God Money.

He categorised Dollars, Yen and the likes which are paper money as Fiat. While he also categorized Cryptocurrency particularly bitcoin as Digital money. He categorised Gold, Diamond, Brass as God's money.

The main thing I learnt from him was what he said about Gold and Bitcoin. He said Gold will be a generational asset and wealth to him and that he has and will never sell it off but will pass it on to this children. He said he had about 3 bitcoin as at then and leaves them as pet in his wallet, saying Bitcoin is the future of money system.

Well which is worth more? I'll say bitcoin because of its usecase. Gold is just a store of value.
