ETH is moving up and down in a big triangle ( ) - as the price is nearing the end of this triangle, we can expect a breakout soon.
I am pretty sure the breakout will be on the upside because Ether or better said the whole Ethereum platform has a lot of potential to grow in the future.
Every touch at the bottom of the triangle will be a good buy opportunity. There is also a possibility that the price will directly break out of its inner, smaller triangle without touching the bottom again.
Ethereum is backed by a very strong developer base and offers so much more than just it's currency Ether. As an example smart contracts or decentralized applications or just its flexibility to adopt new technologies in the future. I suggest to visit their website to learn more about them: https://ethereum.org
So i would say that I determine the pattern with what I see when I look at the chart. But I determine the possible behavior (a.e. the direction of breakout / long-term) with what I think about the news and facts I read and know.
