The secondary ticket market allows the resale of tickets for events like concerts, sports games, and theater shows after their initial purchase. CounterTEN is an online platform that facilitates these transactions, offering users a secure and transparent environment to buy and sell tickets. Unlike primary sellers, the secondary market can have prices above or below face value, depending on demand. CounterTEN ensures authenticity and fair pricing by verifying tickets and providing a reliable marketplace. This platform makes it easier for fans to access tickets, even for sold-out events, while safeguarding against fraud and inflated prices.
