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.
Gold and silver have effectively zero real value, they really don't. They only are worth such insane amounts because people treat them as money.
Bitcoin, USD, Precious metal real value = effectivally nothing.
The only reason anything has value is because people give it the value, people bestow their trust in it and believe in it sincerely, even notes say 'In God we Trust'. The whole idea of accepting money is that we trust the person we are exchanging it with, that it provides value to the good and services exchanged. Fiat,gold,crypto. Anything could be considered worthless tomorrow if people stopped valuing it.
