The developers decided to provide information about themselves or preferred to remain anonymous and not introduce themselves?
Best way to know about that is to be always active in telegram and thier social media sites. I doubt that they will remain anonymous forever. Maybe they are just prioritizing the development of the project first before thier grand introduction.
even if the developers are now actively engaged in the development of the project, in any case they must indicate information about themselves. Many investors are guided by the team and their achievements, and then decide to invest in the project or not.
Like someone rightly said above, there is information about the team on the website, although it is necessary to still do proper digging anyway to be utterly sure where one is investing one's money. However, the easiest place to get to ask questions one may need is to join the telegram group and get all the questions answered.
