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.
Nothing has intrinsic value. Gold has no intrinsic value, same for silver. No one cares about gold and silver beyond what can you buy with it. That's all that matters, if people accept it in exchange and good and services it's money. So Bitcoin is the best form of money we've ever seen.
Gold has an intrinsic value. It surely is not a currency. It's value comes from what it can be used for. It's valuable for electronics as a good electronic conductor for example. Or it can be turned to jewelry that has a value.
You can do nothing like that with fiat or bitcoin. The paper is worth way way less, as well as the material the fiat coins are made of. Ok, maybe one could say that it has an intrinsic value then but it's far from the level of value it has a fiat currency items.
