What is the 7 times 7 rule?

Could you please clarify what the "7 times 7 rule" refers to in the context of cryptocurrency and finance? I'm not familiar with this specific term, and I'm curious to know if it's a widely accepted principle, a strategy for investing, or perhaps a risk management approach. Understanding the rationale behind this rule would be insightful, particularly for those looking to navigate the complex world of digital assets and their associated financial markets.
