Was the Stratos Group B?

Could you elaborate on your question regarding the Stratos Group and whether they were labeled as "B"? It's not immediately clear from the context provided what you mean by "B". Are you referring to a specific rating, category, or designation within the cryptocurrency or finance industry? Perhaps you're asking if the Stratos Group was classified as a certain type of entity, such as a broker-dealer, investment advisor, or perhaps they were labeled as high-risk in some regulatory framework? Clarifying your question would help me provide a more accurate and relevant answer.
