How many loka are there?

Could you please clarify what you mean by "loka" in this context? Is it referring to a specific concept in cryptocurrency, finance, or perhaps a broader philosophical or cultural term? Without more context, it's difficult to provide an accurate answer to your question. However, if you're asking about a unit of measurement or currency related to cryptocurrency, it's worth noting that there isn't a universally recognized unit called "loka" in the cryptocurrency space. If you're referring to a specific blockchain project or token, it would be helpful to know the name of that project or token so I can provide a more precise answer.
