why does it make sense for the most wagered? people can bet 1 btc with 98% chance to win that

,
So what if someone wins by betting
BTC1 once at 98%? I don't see the problem. You can always beat him by betting
BTC1.00000001 or multiple bets with smaller amounts.
The reward has a purpose, rewards activity (betting).
most profit or most lost should be the one to receive the reward if there is
What's the use of
BTC0.01-
BTC0.1 reward if you won or lost say
BTC5,
BTC10 or
BTC20? In either way, you wouldn't care about that at all (so the reward has no purpose).
