Why a Digital Coin Flip is Statistically Fair
Unlike a physical coin that may have slight weight distribution bias or flipping technique influence, our digital coin toss uses a cryptographic random number generator. Each flip generates a value in [0, 1) — if the value is < 0.5, Heads wins; if >= 0.5, Tails wins. This guarantees perfect symmetry over any number of trials.
P(Heads) = P(Tails) = 0.5 (exact, with no physical bias)
