It may be true for any speculation-only asset like AAPL shares or some Ponzi thing, but in case of Bitcoin, it's a good thing when hairdressers know about it. Because the whole point is to accept them as a payment and pay your bills.
It's true, the price is rising now, so people are mostly holding and not paying, but when the demand will be close to saturation, price will grow much slower and people will use BTC to pay for anything, not only USD. That's the crucial difference with the stock market. This will give Bitcoin value outside of speculation on USD price. AAPL is not really valuable if it does not grow (and dividends are almost zero), but non-growing BTC is super-useful to pay anyone around the world with no questions asked.
