All of that can happen because 'disappointment' is the main factor that haunts every Bitcoin buyer this year, experiences often occur for example in 2017, and so on, they don't think about the effect of all that, the assumption that Bitcoin can break through $ 100k or $ 150k is just the opposite.

They must be aware of the current state of Bitcoin, too careless in buying in bulk, slander will not arise if they bought in 2019 ago, I'm sure if they did that time in large numbers, they would have said, Bitcoin is the best in all forms of crypto/digital currency right now, that's for sure.

For that what you see the law of 'slander' in the crypto world, it is undeniable, praised when getting big profits, insulted when disappointed, that's human nature.
