BitConnect was a cryptocurrency lending platform that collapsed in 2018 after regulators and critics called it a Ponzi scheme. Its most lasting legacy is the promotional video of Carlos Matos shouting the name with wild enthusiasm on stage, which became a viral meme for blind crypto hype. Streamer xQC, whose real name is Félix Lengyel, later adopted the shout in his broadcasts, stretching it into his own version. The clip keeps circulating because the reference instantly signals a doomed investment or a pitch nobody should trust.
