For me, this is very common especially with now a lot of social media platforms where people can interact and these people will start to make new trends based on what is really trending right then that will birth a lot of content like jokes, memes, theories, and many more.
Let's take for example the bear season and bull season, which there's no official basis of these seasons.
Yeah right. Even now that bitcoin has plummeted people saying its the start of another bear again well in fact we have just experiencing such set back from market gains for the last few weeks which I think is healthy too to have a good market conditions. Its not like a straight movement is always on the path sometimes some pull back can help to recognize a good set up for all crypto market.
