Yeah, I guess we all go with our "own belief".
Mine is very simple when it comes to giving untraceable funds to anonymous people. It may be old fashioned, but when something looks too good to be true it probably is, and I put into that category "systems" that promise ROI's within very short periods of time.
I also believe that BT was a pure, premeditated ponzi scam, organised by professional criminals who presented a plausible scenario which sucked in a large number of gullible people, with the active assistance of promoters who knew exactly what it was. I would put the Wiermans of this world in that category.
You do what you do, my friend, and good luck to you.
