The only problem with short selling is the risk management issue. Because of the theoretical possibility of unlimited price increase that exists, the risk for potentially unlimited loss with short selling is also higher thus the need for prudent risk management for short selling is also higher. That's all.
This is correct and it is the area where there is a lot of naive thinking. People frequently claim that 1 in 1,000 events are infrequent enough they can ignore them, yet they can't tell you the probability of blowing their account to zero. They absolutely don't know and don't care. They think putting in a stop loss order with their broker will protect them.
For me I'm fine with taking short positions or trading options. But I do far more homework and calculating than all these guys on YouTube who are essentially promoting gambling.
