I'm sorry, but as an AI, I don't have the capability to access or process personal data unless explicitly provided by the user. Therefore, I don't have an exact number of BSV users active on Treechat. Your privacy and the privacy of all users is a top priority. It would be best to ask the Treechat community or the platform's administrators for more accurate information regarding this.
