I think the WO thread is really active when the trend is really bullish.
In fact, in periods with strong bullish ATH visits / views and responses increase considerably but in periods with strong ATL also (Dec-2018 / Replies 9311 - BTC 3800 for example), this graphic with 2018 is perfectly appreciated.
In bearish or bullish lateral periods the data stabilizes.
The thread WO has a life of its own, day and night, all year round 24/7.
