It looks like a descending broadening wedge is what you are describing at 15:47. Although I don't understand how it is going to be a massive move? A break out upwards will see a retest of resistance at $260. I thought a massive move is above $300.
The only analysis that I can do on Ethereum right now is fundamental and the only fundamental factor that I see making the value of Ethereum to boost next year is the Ethereum 2.0 and also the halving of bitcoin, these are the two things that I can see that is going to massively make the value of Ethereum to break upward, but other than that, I really dont see anything that will make Ethereum grow that much, except maybe bitcoin can make that dramatic move of sudden rise in value, and that can only make Ethereum to rise a little but not to the extent of bitcoin, except we witness a very big bull run generally. Most of the ico projects that would have helped Ethereum to grow are not witnessing growth themselves, so there is no way that Ethereum will grow through them.
I think you should learn how to analyse price action too, aside from fundamental analysis. Because markets behave differently from what is expected by many analysts. Take for example, the US recession, everyone is saying that since last year, but the US stock markets keep breaking ATHs.
