Congrats Vino! That's a nice profit so far for a single day...
Do the prizes count towards the competition results? E.g. does Vino's 30mBTC increase his ROI?
No; the daily prizes have no impact on participant's ROI as it is shown in the Leaderboard - they're just an extra prize.
However, this does put Vino ahead in the race to have the daily challenge winnings doubled.

[...] NEW: The winner of most Daily Challenges during the entire competition, will see his Daily challenge winnings doubled!!! [...]
