How many years does a BCD last?

I'm curious to know, in the realm of cryptocurrency and finance, how long does a BCD typically last? By BCD, I'm referring to a potential abbreviation or term that could stand for a specific cryptocurrency, blockchain-related entity, or digital asset. Understanding the lifespan of such a component or technology is crucial for investors, traders, and enthusiasts alike, as it can impact decision-making processes and long-term strategies. So, how many years can we reasonably expect a BCD to endure, given the dynamic and rapidly evolving nature of the cryptocurrency and blockchain landscape?
