I think it's wrong to compare the old bear market history with the future bear market, things could play out differently, I was into crypto in 2019 and I am very sure that there was a bear market years back before 2017, in 2020 there was pandemic, no one saw that coming.
History has its rhythm and mostly its rhythm is repeated many times.
Conditions can be different and it is naturally, nothing can be exactly the same with society, politics, economy and social conditions. However human psychology is the same and does not change with time and it is the most important factor to help history repeats itself. Pandemic is a borrowing reason (one of reasons) to dump the market. If there is no pandemic, market makers will use other reasons to fud and dump the market.
Fast forward to 2023, someone I knew is expecting some kind of a new pandemic to put pressure on the world once again, he believed that the last pandemic was intentional, what do you think?
Intentional or not, we can not say and need investigation but I'm doubtful that we will have good reports about reasons of the 2019 pandemic. I only know that the global markets including cryptocurrency market were dumped intentionally.
A most clearest example is rude oil was dumped to negative price.
Right now some people are still waiting for more downside without any DCA so far, this is a very big risk if you ask me.
It is what you read and heard. Very likely what they are doing are different than what they said or discussed.
