"BCH price going to to down 50%"

Good noon everyone.
Here I come to you with a very unpleased and latest news. Now every people whispering about that bch going to Lowes 50% its price. Is it only for BCH or BTC also?
Ok I am telling you clearly. Nowadays people predict that all cryptocurrencies going to lose their prices at least 50%. There are many reason behind this. well , if I say there are many countries who are not allowed cryptocurrency like my country Bangladesh here is totally illegal cryptocurrencies are. Just few days ago one biggest cryptocurrency businessman take under jail.
Another reason is that biggest cryptocurrency holder Elon Musk said that is not going to sell any of his Tesla car by bitcoin.
Someone says b c h will reach 2000 USD within a few months, on the other hand someone says that all cryptocurrencies prices down at least 50%.
I don't know what is right or wrong. What do you think?
