What is the largest public CRO company?

Can you elaborate on what you mean by the "largest public CRO company"? Are you referring to a company that provides contract research organization (CRO) services within the cryptocurrency or finance industry? If so, it's important to note that the term "largest" can be subjective and can depend on various factors such as market capitalization, revenue, or the number of employees. Additionally, there may not be a universally agreed-upon largest CRO company in the cryptocurrency or finance industry specifically. However, if you're looking for a well-established and reputable CRO company in the broader sense, you might want to consider some of the largest and most well-known CROs in the healthcare or pharmaceutical industries, as they may have expertise that could be applicable to the cryptocurrency or finance industries as well.
