What is a bit of an own goal?

Could you please clarify what you mean by "a bit of an own goal" in the context of cryptocurrency and finance? Typically, the term "own goal" is used in sports to describe a situation where a player accidentally scores against their own team. However, in the world of finance and cryptocurrency, it's not a commonly used phrase. Are you referring to a situation where an investor or trader makes a mistake that negatively impacts their own financial position? Or perhaps you're asking about a specific event or trend in the cryptocurrency market that could be considered an "own goal" for the industry as a whole? Clarifying your question would help me provide a more accurate and relevant answer.
