Yes ,i think it very unable to break right now.bitcoin continously rising and because of bitcoiners who is buying bitcoins to invest and hold it makes the price more higher. If they will sell it after halving we can think that it will down by $500 but it will not go down lower than that price.
After the halving, the price will be higher. Even if people sell the bitcoin, the price will not be below $500.
I am quite sure that $500 will not hold for long once the price start to tank heavily after the halving. It will go up again but it will cost some time. Building up the price cost many months while all that effort can be undone in a matter of a day, or even some hours.
