During bear market (before sideways market starts) you are best to hold only stable coins like USDT and wait for the bear market to end. When a sidewards market begins you can start to buy back your coins and tokens fast at a low price.
With this in mind I assume you are a professional trader, if you are clear that the market is going down and moving towards USDT then I think you should go with margin. Every trend that falls into a bear market, I try to be tough in my Hold,... Besides bitcoin, ETH, and BNB being the preferred choice that interests me the most.
