In NAC, I got to know Dr. Clemen Chiang and had the honoured to hear him in his charismatic voice, promoting his options trading course. This guy claimed to be an options trading guru in Asia and claimed a lot of affiliates and credentials.
I did a search about him on the internet and ended up on a thread in ChannelNewsAsia forum. The forum members seem to dislike him and criticise him and on his expensive products.
I did not really know much about him for now but my friend, Richard Tan of Success Resources seem to be close to him.
Would KIV him for now and see how he progressed in the future.
