If I understand correctly, this means that bitcoin trading and offering investments is not legal in one or more of the countries where you live. Is that correct?
Please read what we have written. What it means is that bitcoin trading of this type could cause legal problems and personal risk and that is why we have no choice except that both of us remain anonymous.
If what you propose is legal in your country, is it safe to assume you're planning on doing some other shady shit to cause those "legal and personal problems"?
Obvious con is obvious.
