Subject: Re: Net Worth of Group
I don't closely know many of these 700 lovely people but 5 have indicated (and 3 for which I know for sure) having a net worth ranging from $20m to $100m.

So you do know some of them. As you live in Monaco likely not the poorest ones, so there is a good chance your sample is not representative for the whole group.

(Just wanting to point out this potential weakness; and no, itīs not to manipulate you into relaying more information.)
