Now Im wondering what they will do with all that bonds wich will have maturity on 2026
It's an interesting topic because people have always been lost between assets that have 3 basic properties: liquidity, stability and appreciation and there's no asset that excels in all 3.
For instance, real estate is stable and can grow in value pretty well, but it requires maintenance that take some of the profit and usually aren't very liquid. You need time to sell a house and get all get all the papers signed. If you buy a car it's going to most likely lose value, so it won't have appreciation at all, but the market will be pretty stable and liquid. If you choose to buy a rare painting, most likely it's not going to be a liquid item and won't generate incredible profit, but will offer decent price stability. Bonds, just like bank deposits offer a bit of appreciation, decent stability and decent liquidity. The problem is that if you account for inflation you come to a conclusion that you're not making any money, just enduring.
What you own depends on your character. I'm a bit of a prepper so for me liquidity is the most important, appreciation is second and I care the least about stability, therefore bitcoin is an ideal asset for me.
I have some liquid and some illiquid assets and out of my liquid ones almost everything is in bitcoin. I have some money in the bank and some cash, but all my fiat money is not even 10% of the value of my bitcoin.
My father, who was raised in a socialist state, used to have 80% in a bank, 15% in cash and 5% in gold. This shows how different we are as people and as whole generations.
