I think PRO-EXPERT should gather experts from different countries. It may be a little difficult, but I think it's good for the project.
Therefore, the idea of some kind of office is not suitable, it will be nice if something like each expert can work and advise from home
I can add from myself that there are already similar projects, but not related to cryptocurrencies or blockchain. This is the SkyEng project. This is an online school of foreign language education. They work on Skype and all their teachers and managers conduct lessons from their apartments.
