What do the letters in ACDC stand for?

Could you please clarify what the acronym "ACDC" stands for? I'm curious to know if it's referring to a specific organization, technology, or term in the cryptocurrency and finance industry. Is it a widely recognized abbreviation within this field, or perhaps it's something more niche? It would be helpful to know the full context in which "ACDC" is being used, as it could have multiple meanings depending on the scenario.
