When you put all your money into the bitcoin you are a beast becuas when the bitcoin is dropping that much you all know that you dont get your money back so everything you did was for nothing
because all your money is gone!
Putting all your money into Bitcoin or whatever other investment option, it doesn't make you a beast, it makes you a dumb person.
No one in his right mind would ever go all in on something that you can't predict the outcome from. Bitcoin fits nicely in that category.
Other than that, even if the price happens to tank significantly, nothing is lost as long as you don't sell any of your coins.
If you realize that, then instead of panic selling, you will use the lower price in your advantage to buy some extra coins with in order to lower your average buying price. That's what smart people do.
