It's really similar. There are several chartpics about it, for example here:

This is from April, and his price predictions are exactly happening NOW.
I think we all agree that 2018 was a much better year for cryptocurrencies, fundamentally spoken. Lots of adoption and hype. In comparison, in 2014 we had the MtGox collapse. The Crypto Winter. Buh.
So I was wondering why the similarity is so significant. And this is my idea:
Is there a trading bot out there that follows approximately the pattern from 2014? That means: The bot continually compare the prices of 2018 and 2014. It would sell every time when, at the same "position in the chart", a significant trading signal is recorded that would make the operator suppose that the bear market could continue. And it would re-buy at similar support levels than in '14.
If this bot was run by a couple of whales, it could explain the similarity of 2018 and 2014.
Even if this bot is not running: I think many of us were rich if they were running a bot like this
(No, I'm not selling bots. Just a crazy, funny idea.)
