Question about PoS: Is there a way to make PoS consume multiple txouts, or is it only possible to stake one at a time?
AFAIK. It depends on how the coins arrived at that wallet, as the PoS is purley based on time or blocks passed since generation. So for example blocks that were originally solo mined will stake one at a time, but if you get 1000, in one lump from a pool it will stake as one block in the future.
