No one really knows what pushed him to do such things which landed him to prison, but it seems like the reputation of Wong Ching Kit was not at all good in Hong Kong. A lot of newspaper actually termed him as "Chinese Crypto scammer" and he has few ongoing police cases against him.
Some newpaper even called him as "Trevon James" of China. So it is well understandable that he has a dubious reputation in his own country. The less such kind of people joins this forum, the better! We really don't want to get associated with any kind of dubious activities here!
