The value of gold, silver and platinum is determined by two factors: there is little of it in nature and you cannot take more at will and it does not oxidize, which ensures good storage.
I really don't know about you, but in my country you can't take gold out of the bank. You buy gold from a bank and it stays in the bank longer without the possibility of taking it out. What a joke. Guess what happens to the bank and the gold in it when the economy collapses.
And now look at Bitcoin. there is a little of it, you can't increase it at will, and it's convenient to store. Does it remind you of anything? And it's always with you.
