A fair coin is tossed 100 times to create a sequence of heads and tails. A participant is allowed to ask 1 yes or no question (e.g. was the first coin flip heads?), then plays a game where he tries to guess all 100 coins. The participant is awarded $1 for every coin guessed correctly, and loses $1 for each incorrect guess. Find and prove an optimal strategy.
