These are good thoughts, and @Gold has a great response . But a few more things to remember:
The funded staking option may not always be available. Nor will the percentage necessarily remain static. I don’t know of any plans to change it at the moment but it’s an option should it become necessary.
Additionally, the 65% isn’t just going to line someone’s wallet. It’s a tool for the DAO to further remain autonomous. It requires funds, and this is one way of generating them. There is room for discussion and change, but it’s not an apocalyptic scenario. The price of prv fluctuating has been a certainty from the start, and the staking mechanism was designed to account for it. That’s why it’s good to be a validator now, it will get harder in the future. Yet if it gets harder since prv increases in price, the rewards are balanced. There’s much more to address but someone from the team will be more able than I, so I’ll leave it to them! But all in all, these are important questions, so good eye @sato.
