Guys I dont know what to do, should I invest in Gold or Bitcoin. Gold is more stable I know. But the bitcoin development is crazyy, imagine if you have bought it before 20 years...

Judging by your first answer on this forum, you have the finances to open a supermarket in Spain (just what I see), which means your investment involves a significant amount.
Why not then diversify your investments into both assets that concern you today?
The same money i could invest into active business, like a supermarket in a sunny country like spain and the rendite will be maybe much higher, its a headache topic. What do you think, and what do you think about investing in Gold instead of Bitcoin?
