You are looking for a private investors with no information about what they should send you a private message for. I don't even see the big deal of you not making link known the public. So the investors will invest in a project they don't even know how the public will react to. I wouldn't bother myself if I was an investor
Exactly, am hiding the links from people like you who just want to say anything about a project which we have invested over $100,000 on, we aren't looking for advice on the project we are looking for investors if you aren't then its better you don't respond at all.
Thanks.
