If you have much money but you aren't use it, it's better to invest it than save the money. So you can earn passive income from your idle money. It's really good imo.
Of course it is... But atleast you should have knowledge on where you are investing your money and how those investments works, coz if not, instead of earning, you will end up losing those supposedly passive income...It is much safer if you save it and just invest it after a thorough studying on those investments that you want to put your money in..

Why you are just going to choose saving only if you are going to be able to do that both? For me I want to do both and going to keep doing both of it.
Since we are in bitcoin, so if you are going to hold a lot of bitcoins today. Then probably you are also investing to it.
So you are doing both, saving and investing at the same time.
