Do alien numbers expire?
I'm curious, could you elaborate on the concept of "alien numbers"? As far as I'm aware, in the realm of finance and cryptocurrency, we don't typically deal with such terminology. Are you referring to some form of unique identifiers, serial numbers, or perhaps a metaphorical concept? If they're indeed some sort of numerical values attributed to extraterrestrial entities, could you explain the context in which they might "expire"? It's an intriguing question that requires clarification to provide an accurate and relevant answer.
