It'd be great if it's true, but previous event doesn't guarantee future event. So personally i don't believe same pattern will always happen. And this chart analysis doesn't consider major event (such as SegWit activation and BCH hard fork on 2017).
there is a light now because look at the movement now . it seems like OP's sharing is coming to close in what is happening now meaning we are close in repeating itself?
https://coinmarketcap.com/currencies/bitcoin/OP, what you shared is really a good hint for us to observe before following and might bring us better result in the sooner phase .
