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.
I thought you were saying money kept in bank won't yield anything except if invested. Well for me I think money in the bank or in private wallet are still wealth, because they all have same value. The difference is that one is in centralised form and the other is in decentralised form. Anywhere you keep your money doesn't really matter. What matters is this. " Any money not invested will not yield anything". And it's not a smart financial decision, to keep money in cash irrespective of the place you choose to store it up. At this age it's not expected that we keep money in cash. Instead of keeping money in cash, invest it. But just know that if you don't invest your money, where you store it doesn't matter. Because none will add any value. Rather they will depreciate when inflation hits. And the depreciation will affect both. Be it stored in bank or in wallet.
