Buying a stock/bond/asset comes with the intrinsic belief the value will increase. Being more specific, purchasing any speculative asset comes with the belief that the thing I am buying will increase in value relative to the thing I'm buying it.
The reverse is also true for selling a speculative asset.
Now that that is out of the way. Let's continue cherry picking as you've done and consider traders that specialize in short selling companies they deem as bad market actors. What do high profile short sellers do? They go on all sorts of media rants warning about companies/assets ect TO WARN PEOPLE AND INFORM THEM (legitimate or otherwise) for their own gain.
Cherry picking these ideas with respect to crypto is totally naive.
Some people use BTC to pay for VPNs, drugs, or simply to get cash out of their country. There was a lot of speculation that the big spike in BTC a few years back was the Saudi royalty trying to move cash out before MBS cracked down on them.
And that's why short-selling is so important.
Orthodox economics is severely underrated.
Oh, and bitcoin got a decent short-selling facility with the futures trading a while back.
(No clue why you are getting downvoted.)
When you buy (e.g.) real estate you can get value out of it without thinking about selling it for a profit later. Especially if it's your primary residence.
Same with most vehicles: they depreciate over time, but there is utilitarian value in the asset. Unless it's Steve McQueen's Mustang or something.
Not every "asset" is about ROI.
Real estate, and the various loans and derivatives, all eventually end up at real, productive assets that you might want to own.
Stocks and the various index funds and derivatives, all eventually end up with ownership of a company. A company which, if profitable, can pay dividends back to the owners.
I'd argue that it's a much rarer class of investment vehicle which is purely speculative.
Suppose a company makes $100,000 per year and this is expected to continue. How much would you pay for it?
Now, suppose it makes $100,000 per year, but for some reason once you have it, no one will buy it off you. How much would you pay for it?
You'd pay less in the second case, but not that much less. The company has a value which it gives to you for having ownership of it.
Meanwhile, bitcoin produces....$0 per year for owning it. The only value is in sale at a higher price. You have to bet on appreciation.
This is something fundamental people often misunderstand about, say, stocks. The price is set by supply and demand for the stock, but the value is determined by the cashflows. Usually price and value move at least somewhat in sync. But if stock markets went insane and valued everything at $0 for some reason, you'd still want to own companies.
A thought experiment to show the difference between price and value. Bitcoin currently has a price. No actual intrinsic value other than the hope of value in the future.
I don't think that whether it has this property (and value) is in question - the question is how much of BTC's price is fueled by that value.
Unless the income-producing aspect of the business is dependent on you, there's always someone willing to buy something that produces money.
In such a world, the $100,000/yr business still has value to you. That was the point.
At the moment I rather see people buying stuff that they think other people might deem valuable in the future, e.g. motivation behind buying TSLA is similar to buying BTC.
Given the huge amounts of money that investors will invest in companies that make negative money every year, I think this is (perhaps unfortunately) not at all true in the real world.
Even if this company owns the whole world at the end, is it worth even $1?
If I get non-voting shares that do not pay dividends, then these aren't shares, they're just useless scraps of paper. If the only utility I can get from them is being able to point out that I "technically" own the entire world, it is indeed useless.
Maybe I'm willing to pay a dollar for it but certainly not two.
*In the tech hysteria, it's easy to forget that this is where the fundamental value comes from.
