As you now can see your groundless speculation were wrong. Unfortunately, even after so many years of existence of bitcoin, there are still people who think like you. None of you wants to study the history of bitcoin and the crypto market as a whole. Because if you had a little interest about it, then such statements didn't appear in your head. After all, if you don't read anything, you can just logically think.
Thousands of people earn colossal money for bitcoins and crypto currencies. And do you think that they will take it all in one moment and give it up? Do the whales who keep hundreds of thousands of bitcoins on their wallet simply will not do anything when  they see that bitcoin is dying?
Just think a little, and such thoughts will never visit your head again.
