Leverage in a bear market? Huh?

[grayduck]

I saw someone mention in a YouTube video that you could leverage in a bear market to minimize your losses or something like that. What is that? How can I do it? It seemed like they meant trading something that was experiencing a loss for something that was experiencing a bigger loss. For example, if Ripple is down 10% and Tron is down 30%, they seemed to say you should sell your Ripple for Tron and that would somehow mitgate your loss. Or the other way around? I didn't understand. They weren't talking about margin trading.
