Replying to the title first, Bitcoin is not backed by the Dollar and it would be pointless to back it by Fiat. That would redeem the entire purpose of Bitcoin null.
But you probably meant to say what happens if the Dollar collapses considering Bitcoin is usually priced in Fiat. Well. If the Dollar collapses, first and fore most the whole world is going to be doomed for a while. No body would care about Bitcoin or Fiat probably for a reasonable time.
If they did care still, Bitcoin will PROBABLY continue to exist and have value. Because it will continue to be as scarce, it will have the same properties. Long as the Internet is still alive and well, Bitcoin will continue to be used without a doubt. Particularly considering there would likely be a significant amount of hatred or uncertainty about Banks, Bitcoin would be a great solution as it is Decentralized.
Satoshi Nakamoto (Who ever he really is) simply made Bitcoin to give a chance to geniuses like him to be rich
he made it so only smart people who live in the west can be millionaires in the future and he did it I mean look at the richest people who made there fortune form Bitcoin and other Crypto currencies, all of them have 130 IQ at the least and all of them sold most of it.
What the hell? Hand me out a source of ALL the people who became Rich from Bitcoin being over 130 IQ? This sounds ridiculous and so made up.
Bitcoin isn't real, the money that those people got is.
change my mind!
But then Money is not real either. What you get with the Money is.
Bitcoin is real. It is valued by us who are using it and it is valuable to most of us here. I would continue to pay for Bitcoin even if a whole piece was a million Dollars. I just think it is a value and I do think it will never permanently lose the value it has. I could be very wrong. Who knows. It remains to be seen.
Many things are 'not real' if you think about it. Got something of value that other people think is worthless? To you it is value, to them it is nothing. They could throw it in the garbage can and go on with their day. But then there are other people who would pay the value you think it has. Or maybe even more just because they value it too. This reminds me of Schiff, who always said Bitcoin has no value and is equal to zero but now I bet he regrets deeply.
Bitcoin is a value. There is no point in changing your mind considering this is a fact as it is priced close to 70 THOUSAND Dollars and has only been rising for more than a decade.
