No money, just fiat currency. Money has inherent value such as gold and silver, both of which have a 6000+ year history of being a reliable store of value. All currencies are inherently worthless and eventually go to zero value in an average of 45 years. Regardless, it is not investing, but rather speculation...and it is fine, as long as you can afford to take the risk..... and have a chair when the music stops.
Let me know how it works out when you go try and buy something with gold and silver right now. While you may be able to buy something its not going to go well. Not only that but silver and gold are speculative as well.
Don't be afraid to look in the mirror.
PS all investing is speculative....
