Got to agree with above. Anything that gives a 15% return in a month could be linked to something like a South American drug cartels. Although I do remember Thai money lenders hanging around Soi Nana back in the 1980's demanding 10% a month with motorcycle riders doing collections. Getting involved with either is not good and shows the investors didn't activate their brains.
Odd? Up until now the fact that there were two farangs in in the group would have been emphasized, capslock, letters of fire 20 feet high. Here, it's just mentioned in a reasonable manner. What could have caused this change in writing?
