Bitcoin - a fantasy currency with potential ?


Admittedly, I don't really understand how the blockchain works. Well, many computers store values, but what values ? A number and nothing else ?
What is the real value of a Bitcoin ? Who is behind it ? Or is the whole thing just a grandiose idea, but nothing more.
The method also shows what our money is worth in the end. Currently, money is not even printed anymore. It is a number in a computer.
Covering the money - missing! Only faith keeps this system alive.
What if the people lose faith in the value of money.
Back to the Bitcoin. Is there anyone here who can explain to me what value a Bitcoin represents in real terms ? Or does it work just like our normal money: as long as everyone believes in it, it works.
