What comes above mega?

Could you please elaborate on the hierarchical sequence of prefixes used in describing large numbers, specifically what comes after the prefix "mega" in terms of magnitude? I'm curious to understand the progression from mega to the next level of numerical representation. Is there a logical progression from mega to the next prefix, or is it a more arbitrary jump? Additionally, could you provide an example of how these prefixes are used in real-world scenarios, perhaps in the field of finance or cryptocurrency, to denote large quantities or values?
