Price of asset can't go lower than zero if it gaps down to zero. A short asset could balloon overnight on acquisitions/major breakthrough/etc.... I suppose you could place deep limit orders that trade outside regular hours to avoid it....
But the loss mechanism is still the same. If the price goes against you, you lose, regardless whether you were long or short. A fall from a $1K price to 0 is still devastating just the same. If you are concerned about the potentially unlimited losses with shorting, just short less.
H&S being built by the looks of it. Since it's monthly we're looking at a major crash earliest late next year.
You haven't heard of this fantastic phrase "unable to locate"? Going short isn't exactly like going long. The dynamics are very very different but from a distance it all looks the same.
Theoretically the sky's the limit against a short. Theoretically. Reality though is that gaps up/down happen about equally often, as well as similar percentage moves.
No matter how it looks and how it may sound, you have to remember that all is not lost and this is not the end. These are the natural changes that occur everywhere, so do not despair, but you need to hope for the best)
