Question:
What happens, when all available Spendable balances in all currently available (online) wallets go to Staking, and there are ~150-200 confirmations left before the Interest awards begin getting confirmed and coins released from Staking back to Spendable? With no Spendable left, who finds next block?
My understanding of how PoST works might not be right, but aren't the staked coins the ones doing the work? If so, it doesn't matter how many coins are in Spendable, as these are doing nothing and not contributing towards finding the next block.
