I think that the risks do not depend on the size of the team, 1 good specialist can replace 10 inexperienced employees.
The true truth, it is a pity that many simply do not realize this. Judging by the information from the website, the team members have some experience in their field.
I was surprised that the project team is completely open, there is a lot of information about them, even their mobile phone number
Because the team does not make sense to hide itself, since this is a real project and not at all scam, any information can be found
