What people also are saying is true the bitcoin is a sort of depending on it.
bitcoin is not depending on anything else.
it is a stand alone money without the need to any other currency.
the fact that its price is measured in USD or any other fiat for that matter is only because we need something to measure it with. nothing else.
In a sense that is correct, Bitcoin is not depending on fiat. But price of most products or services sold in bitcoin is adjust according to the fiat currency specifically USD.
No one sells something for fixed 1 btc when price of bitcoin falls or rises. they will the the bitcoin amount accordingly, so in other way bitcoin is dependent on fiat currency
This state of affairs is essentially the same as with, for example, gold. But no one would ever dare say that gold is depending on fiat (this is ridiculous even to write) and all despite the fact that you can buy with gold even less than with Bitcoin. As far as I know, there are no payment cards linked to gold vaults, lol. But there are a lot of Bitcoin payment cards linked to Bitcoin wallets. These cards are as convenient as any other payment card out there...
Nevertheless, quite a few people still think that Bitcoin somehow depends on fiat, and even more so on the American dollar
