Well to be fair, bitcoin itself isn't tied to anything of value. So it really has no value other than perceived value - the value people attribute to it in their own head. That is one of its weaknesses.
That’s a common myth. Bitcoin’s
price is not directly caused by subjective perceptions: It is a result of the market, based on supply and demand. Perceptions are
one factor in the “demand” side of that. There are other factors to demand; and perceptions do not alter supply.
Ultimately, Bitcoin’s
fundamental value derives from its facilitation of productive economic activity, which would be costlier, infeasible, or impossible without Bitcoin. I know that I have done productive non-Bitcoin, non-market business with Bitcoin, which I could not have done without Bitcoin. That’s not extraordinary: It is being an ordinary Bitcoiner who uses Bitcoin as money, rather than a purely speculative buyer who just wants “number go up”. The more such people they are, the higher the organic, non-speculative demand for BTC.
This discussion of economics is far off-topic for the development forum. I feel obliged to answer something that is more usually nocoiner FUD or newbie confusion. If you have further questions about this, I refer you to Bitcoin Discussion or Economics.
Yes of course the value goes down since nobody needs the 5th fork of bitcoin that has nothing else than a little bigger block size, but thats not the point. If you for example don't like the Bitcoin logo you could also create a fork with a better logo and nobody would use it. Still it would not mean that people are not satisfied with your new logo.
That's a minor issue with bitcoin is that someone can make a duplicate copy of it and
the only difference between their copy and the real bitcoin is the popularity of one of them.You talk like a Bcasher with Bitcoin Envy. If you suppose that the
only difference is popularity, your gross ignorance is showing (again).
Bitcoin forks often retain design flaws that Bitcoin has fixed, such as the transaction malleability fixed by Segwit. (Part of my wrath at Bcashers is anger about how by opposing and FUDding Segwit, they sought to preserve a security flaw.) Many of them are ill-maintained. None of them has Bitcoin’s network security against double-spends (and indeed, some of them have been 51%-attacked). This list of differences could be much continued; but I think most people with the knowledge level to post in the development forum are already very well aware of the diffrences.
