I wouldn't shut off such an ICO immediately. Perhaps within the 10 million they want to raise, they have included a budget for hiring more staff to help them develop and run the project or even outsourcing part of the project. I think a legit ICO, even if it starts with 5-10 employees would update their community as they grow in partners and add more people to their staff.
It will worry me if an ICO amntaking part in has few employees because that tells me that the fellas are only together to scam me. Another point there is that any ICO without a developed project in mind will.end up not producing any product. It is always ending in a scam. Am very careful about this things.
