My point is there's not even evidence to support online chatter turning negative. Any topic that is polarizing and growing in terms of chatter will produce more positive/negative blogposts and youtube videos. I could write this blogpost substituting in anti-vax sentiment for example pretty easily.
I didn't assert whether sentiment was changing or not, just sharing the pattern in case someone reading hadn't thought of it. Sentiment is easy enough to check. I'm not doing crypto homework though.
