the good point of bitcoin ... is that you can print paper money if you want : https://www.bitaddress.organd, 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.
Every currency as we know it today as no value backing it. The bank basement full of gold is gone long time a good. Currencies as we know are no more than Debt titles.
That we believe will have value to trade for something. Bitcoin is the same but the trust base is not the state or government but a decentralized algorithm...
