That shorting of "assume I have it right now without me having it, and I will pay for it later" is the root of all the problems in the crypto world. I mean that makes it profitable to drop the price of bitcoin and people think that it is somehow okay.
I am also not a fan of shorting. But it can be done by those willing to take the risk. A complete risk free building of portfolio is possible and hence shorting should be done carefully knowing the risks and not as a sudden decision. Most of the time it is a sudden decision indeed because it happens during a market crash not on a stagnant or rising market.
Also the notion taking loans for trades and what shorting looks like is a cause of debts and endless cycles of despair. These can be completely avoided but difficult to stop if stuck in.
Hence I never recommend shorting to newbies but only experienced traders. I myself never actually do it.
