How to inverse crypto?

Could you please elaborate on the concept of 'inverse crypto'? Is it a strategy involving short selling or put options in the cryptocurrency market? How does one go about implementing this approach? Are there any specific risks or considerations that investors should be aware of when attempting to inverse crypto positions? Additionally, could you provide some examples of how inverse crypto strategies have been used successfully in the past, and what kind of returns they have yielded? I'm particularly interested in understanding the mechanics behind this strategy and how it can potentially be utilized in a diversified investment portfolio.
