Binance is a major cryptocurrency exchange, and its mobile app uses a short electronic chime to flag price alerts, orders and account activity. Traders began lifting that familiar notification sound into memes and short videos, where a single alert already suggested a market move, while the four-times version exaggerated the flood of alerts during volatile trading. It spread through crypto communities on social video platforms, where it now works as shorthand for watching charts, chasing pumps, or reacting to sudden drops without needing any explanation.
