Although there is truth in some of your words, the same has been said for the past week even at prices like 500-600. The actual truth is that nobody knows where it will go because this is actually an exciting projects backed by institutions, banks, companies not like other altcoins that are made for a bunch of nerds concerned about privacy to buy drugs. That's what killed the whole scene, Ethereum is the first project (a very professional down, top to bottom) that will cater to a very interested audience. Of course it can become a little irrelevant with the course of the months and years and that's about it.
However, it holds the chance to completely change the way we do things, banks for example are looking for a blockchain standard, imagine if in some months the major banks start to adopt Ethereum not just flirt with it? And then comes development of dapps, etc, that's why there's so much interest in it, the potential is really unlimited.
The other projects are just nice hobbies compared to it, taking out all the BS bitcoin clones, nobody even uses Bitcoin they sure won't use freaking Litecoin or Dodge or whatever privacy enforced sh*tcoin they are pushing. It won't happen.
I've been fully invested in Ethereum from the get go, don't get me wrong, but I also have my feet planted on the ground. I have no doubt ETH will be a strong contender in the crypto world going forward, until replaced that is. I'm very happy I got on board early on, but I try not to lose sight of reality, especially when it comes to my money, and the reality is there is millions of Eth holders not in the market, and it will only take one or two whales to wipe the entire buy market out. I don't like those kind of risks, nor should you. So it's worth mentioning. After another year or two and ETH becomes more widespread and into many more hands, not a handful of whales, it will be much more stable.
Right now they are using buy walls to heard sheep into their sell walls. That's all that is happening right now. Why sell to the market when the sheep willingly gobble it up? These buy walls, these guys got ETH either FREE or for a few pennies. They could give one rats *ss if somebody dumps a few k into their 50k+ wall. They know in the end the sheep will gobble it up at the next wall. They started doing this around the 400k mark. Watch next time you see the walls go up, and watch how the sheep flock and gobble up the higher wall.
