You hold nothing If this money not backed by something real or atleast with cash.
The BONDS treasuries not something for sure but they are more like coupons wich show's how good situation the goverment and other people are to keep value of money.
I told my own bank show me stablecoins, cash,or cryptocurrency or gold equlaint with money i have otherwise i own only numbers wich doesn't mean anything just the numbers on screen.
It's mature way to look finances i don't want to my wealth backed by bonds coupons it's speculative and we never know If they keep holding any value at all.
I stay my point: something i can hold in my hand or private wallet that's real wealth and the wealth i can count on.
Stop talking nonsense. So according to you what you call money must be tangible and anything short of that is not money right? Did you also know that cryptocurrency is just some bunch of codes that's displayed on your wallet as numbers?
You may not trust the bank, and it's fine to diversify your wealth in gold, landed properties, real estates, crypto but you still cannot do without fiat. Except, of course you want to go back to the primitive age and live in a cave.
