and, it's real value !
You're right that bitcoin can't be printed when more is needed.
You're wrong that bitcoin has real value. The value is perceived because all of us place value upon it...just as we do fiat currency.
There is no tangible thing that supports the value of bitcoin, that can prove there is value to it.
There's no Gold, no Silver, no other tangible item that exists in the world...just the promise that only so much bitcoin can every be mined and that the validity of transactions and balances are verified by the community that uses it.
What is money? Dollars/euros etc don't have value either.
Even gold and silver don't really have value unless you want to build a smartphone or computer or something.
Real value is in food, clothes, luxury items like cars, things you can use.
Gold and currencies only have value for as long as people are willing to trade real wealth for it. In that sense Bitcoin is as real as any other currency.
I think you're confusing "value" with "utility." Utility and value are closely correlated, but they are different. Gold, silver, fiat, and crypto all have value when any person decides it does and will trade something else for it.
