This binary model repeats independent win-or-lose rounds with fixed odds and payout. A loss returns zero; a win returns the total multiplier. All planned stakes are placed, with no balance limit, stopping rule or fees. Expected values are averages across many sessions; standard deviation describes spread, not a guaranteed range. Custom inputs do not verify any site's fairness or predict your next result.
