Kun has become an sudden sensation in the streaming platform, breaking the 1 million subscribers mark in less than two months. His streams have had peaks of over 30.000 simultaneous live spectators. During the suspension of regular tournament play due to COVID-19, Sergio made his foray into the game streaming scene, for the benefit of those engaging in social isolation – and for charitable causes as well. Kun has been active playing 1-on-1 NBA2K games versus Courtois, winning a Spanish FIFA tournament with his own team, and achieving a good showing in the Virtual Formula 1 Grand Prix of Barcelona. Sergio took online streaming by storm in April, become the streamer with most growth on that month with 800.000 subscribers. He passed 1 million subscriptions on live-streaming platform Twitch by the end of May.
