Well, I think it's too early to start talking about it, it's too big a result for them for such a small amount of time, but over time they will be able to achieve this and developing to grow in the economy.
The recent pump is not convincing though, so I also think its too early to be happy for that. But of course it will happen in the right time especially with ETH. We all know how giant this coin is and the price can really go up high easily, we just really need more time for it. $500 for ETH at the end of 2018 is fine for me, and maybe we will enter in another bull run this year that can pump the ETH.
