How does rain secure cryptocurrencies?

Could you elaborate on how rain, as a phenomenon of nature, actually secures cryptocurrencies? It seems like an unusual connection. However, if we're referring to some technical aspect or security measure, I'm curious to understand the mechanics behind it. Cryptocurrencies, by their nature, rely on cryptography and decentralized networks for security. So, how does the concept of "rain" fit into this framework? Is it a metaphorical reference to some kind of refreshing or cleansing effect on the system? Or is there a more literal interpretation, perhaps involving some innovative cooling or waterproofing technology used in cryptocurrency mining or storage? Clarifying this would greatly assist in understanding the question's intent.
