The ether is positioned not as a crypto currency, but as a platform for building decentralized applications.

In my opinion, the ether will not get much popularity as a platform for decentralized applications because of the huge volatility of all crypto-currencies. Think, 3 months ago 1ETH cost $ 20, now 20 times more expensive, this means that now to work in a decentralized application on ether, you need to spend 20 times more money. And further can be even more expensive. And imagine that someone will make a forum or social network on the ether, and in order for the user to show some kind of activity - to write a message or like a message, then he will have to pay for everything... This is insanity...
