Sort of. After two weeks I was at zero, and the prospect of going all in at the expense of the rest of life to maybe get 50th place and 10,000 sats was not worth it. Then again, somebody won a prize with only one post I heard, so who knows.

The rewards are more incentive. Without daily rewards, there is less incentive. It's not all or nothing. It isn't that regular zaps isn't enough, it's that when that's all there is, there is less incentive, therefore I spend more time elsewhere (such as fiat job).

Rewards are 10% of the regular zaps redistributed to some people. Daily rewards meant, therefore, more than 10% more sats than usual - I guess 30% more since it was the top 1/3. MSM meant 0% almost guaranteed.
