It's not definitive, but seeing an anonymous team behind an ICO project is not encouraging.  Though this industry is presently unregulated, that could change in the future.  Certainly individual registration of representatives, and a minimum degree of transparency would probably be implemented along the lines of what exists for IPOs and private placements in traditional equities.  I would take extreme caution in approaching any ICO, especially one where you don't know the identities of the creators.
