I have to disagree with you in that point. Shorting isn't the cause of max loss if your trading skills are good and you know futures trading very well then shorting could give you short term good profits. In order to gain profits in short positions you will have to have an amazing strategy, and a mind that can avoid fear of loss. You should never go with more than 2x leverage and you should also divide the funds for hedging. That way you will earn enough profits and the losses will be minimum to none.
Problem is, even on 2x leverage, it still only takes a 50% spike to bankrupt you. Yes, you can use stops, but those are prone to stophunts and scamwicks. I'm generally not a fan of hard stops for that reason (I do love dynamic stops).
This is the P/L on a short vs. a put option:
PictureYou'll see that the put option outperforms the short in almost every scenario (higher gain, lower loss).
This one is somewhat right and somewhat wrong. You won't gain infinite profit with the longs. You should also keep in mind that you'll have to pay a funding fee every day. In case of Binance it's 8 hours duration when you will pay funding fee. The exchanges change those fees every once in a while.
Other than that longing also has risks if you are trading a wrong pair. Some altcoins have gone below 100% in past and that means people who have put money into the long positions have lost everything. I remember that thing happened with Terra Luna when many long holders funds have been liquidated during that disaster.
Highly positive funding (0.1%+) changes the risk matrix slightly. and makes shorting more attractive. If you have to short a perpetual future, at least choose one with high funding. Not always easy to find though.
You might have used higher leverage and you might have not divided the funds for hedging. Otherwise, it's possible to earn huge returns with shorting. I have been earning with shorting and I can definitely say that it isn't bad if you know the market conditions.
It's still possible to earn good money when shorting perpetuals, if you know your shit as a trader, but as the blog post says, the risk/reward is inferior to put options. Thats why I only do put options now.
WIth put options you can easily earn 500% on a short. Not possible with perpetuals (unless you use high leverage, which you shouldn't).
