The audio comes from Carlos Matos’s famously energetic BitConnect presentation, which became widely shared online during the cryptocurrency platform’s rise in 2017. Clips of his booming greetings and emphatic delivery were cut into remixes, reaction videos, and short meme edits. The repeated “hey” remains useful because it is brief, recognizable, and easy to synchronize with entrances or visual reveals. Its association with exaggerated promotional excitement also gives the clip an ironic edge in videos about questionable ideas or excessive confidence.
