when you see they advertise high returns, can assume/suspect it's a scam.
The simple truth is, if it works, they would have already earn enough themselves.
If it haven't work, why are you joining them?
If it's such a good business, banks would have loan them $$. Their financial statement must be quite bad to begin with.
Next, you can try googling their company's name. Remember that the name must match exactly,
e.g.
global asset advisory is not the same as global asset advisors.
If there isn't much result, it's not good.
If there are results that tell you it's a scam, you get it.
For this one, you get to this page

but one ain't even sure the bird nest company is related to the global asset advisory one, they only state that they are the organizer for the seminar.
Anyway, googling benny tan amgprofitable you would get to this page
http://www.amgprofitable.com/eng/tml.html,
from that, you get to their fb page.

their facebook page is not updated since 2012,
don't need to be a genius to tell how the business went, if it even got started.
You can even go further and click on those likes you see in the facebook page to do further investigation.
or this page

nothing much saying they are a bird nest company, so it's a investment company?
You can try contacting this lady who actually has worked there for 1 year+

she stopped working there in december 2013.
Anyway, always DYODD. It's your own $$.
