Unlike most other metals, gold is suitable as a currency partly because it doesn't get 'used up' in industrial processes in any significant way (where it is used its malleability ensures only tiny amounts are necessary - one gram of gold is enough for a square metre of gold leaf). Similarly, its use as jewellery is not so much to create beautiful objects, but as small portable stores of wealth[1] - in the world's biggest gold jewellery market (India) the price of jewellery is pretty much the same as the price of the raw materials (i.e. gold).
[1] Funny story. I once had a colleague who married an Indian woman in India. He came back to work wearing a lot of gold jewellery (watch, bracelets, rings, necklace or two, etc). Even he thought it was ridiculous, but he felt obliged to wear it. I had to explain to him that he wasn't given all of it with the expectation that he'd actually wear it - it was basically his wife's family's way of giving them money.
It seems likely that the dominant currency of the future will be heavily inspired by Bitcoin--but will it be the same blockchain Bitcoin uses today?
Seems unlikely to me.
The ICO's are like the Webvan and Amazons - similar to how businesses used the Internet to serve their respective industries, we are now using ICO's to serve specific markets.
Rentberry for Rentals, Enjincoin for Games.
With so many new ICOs, it feels like the early Startup Scene but now it's with a focus in Cryptocurrency.
How so? I buy lunch with Bitcoin and a few weeks ago I paid for a car repair with it. If I need more, I just go to a bitcoin vending machine near by.

(Assuming you bought it for cheaper than the price you transact at)
While this may seem pedantic, it is important that people do not rely on BTC transactions for anonymity. Perpetuating this myth may become dangerous for some Bitcoin users.
It's the same with expensive paintings. A painting is considered to be beautiful (some are actually ugly) and have some deep meaning only after it's sold for a lot of money.
I too thought most of this "throw paint onto a canvas and charge rich suckers thousands of dollars" is bullshit. But after seeing some Picassos IIRC, I realized, yes there is a method to the madness.
Even if the painting wasn't displayed in a fancy museum, I think I would still have thought it was "special".
But those "artists" that pour paint onto the canvas - complete bullshit.
If a five year old can do it - it's not art except to the parents of those "artists"
Reason: it's complicated. But something that's DEFINITELY required for this to be possible is scarcity. The artist is not alive any more. It would never sell for that much if he were still alive.
True digital scarcity is a hard problem to solve (because computers are good at copying things). Bitcoin was the first system that was able to solve this problem.
This does away with the idea that gold has no relevant value outside jewlery.
