What is QB box?
Excuse me, but could you please clarify what you mean by "QB box"? I'm not familiar with this term in the context of cryptocurrency or finance. Is it a specific hardware wallet, a type of trading platform, or perhaps a software tool for managing cryptocurrency portfolios? If you could provide a bit more context or information about the function or purpose of "QB box," it would help me to give you a more accurate and informative answer.
