Every time the market goes down, it's not only the newbies who panic sell that are doing it but those who are professional traders are selling as well because they know how to short the market and if you have observed in the past, it is more profitable to short it because it's going down too fast compared to going up that's why they are at an advantage when it comes to shorting and when it drops, it drops hard.
Personally, I don't think that naked shorting makes sense unless you have insider info. I recall when a couple years ago some dude lost something like 600 bitcoins (when the price was still below $1000). He obviously expected that it wouldn't go above that mark and would soon correct, but it didn't happen and the price went exponential well beyond 1000 as we all now know. And in the end this hapless trader had his position forcefully liquidated by the exchange. Shorting makes sense when you are hedging, for example, against volatility or even exchange itself and their dirty tricks, while naked shorts can be fatal to your account sooner than you think
Always remember that with shorts your profit potential is limited while your losses are limited only by the balance of your account
