Why bitcoin can make a much bigger lower low.

After every major cycle we had an 86% average correction down.
This cycle was from $150 to 20000.
In what world is that Healthy?
Why do people think that when someone says that bitcoin will go down to 1000 they are crazy and fear mongers?
They dont wanna accept the fact that everything can collapse even bitcoin.
I think i am even to optimistic about thinking that 2000 will be the bottom.

Buy when the fear and greed index is at -1000.
