The online docs state in relation to being selected as a slot leader:
not all stakeholders (stakepools/nodes) participate in this election, but only ones who have enough stake (for example, 2% of the total stake)
So would that be 2% of all cardano staked throughout he entire system or is it restricted within the context of a node/stakepool, ie owner has at least 2% of tokens staked within pool/node
If it was the entire system, assuming we had 50% of circulating supply staked then in order for a node/staking pool to be in the running as a slot leader they would need a minimum of ~260m ADA? is this accurate?
