What is the minimum stake in Rocketpool?

As a keen observer in the cryptocurrency and finance world, I'm curious to know the specifics of Rocketpool's staking requirements. Could you elaborate on what constitutes the minimum stake for participants in the Rocketpool network? Understanding this threshold is crucial for potential investors and stakers alike, as it informs their financial decisions and risk management strategies. I'm particularly interested in knowing if there are any specific token or Ether requirements, and if these minimums are subject to change over time. Your insight into this matter would be greatly appreciated.
