i have been a trader for 2 years, and i were scammed too and learn sth. and i heard so many scammer story on alibaba. and most experienced businessmen said that it depends on "sixth sense' to avoid cheating.

Perhaps i am still too young and i always do business on trust, if i trust you, let's make money together, if not, go to the ****, sometimes i think i lose some real buyers. finally all traders are desiring to expand their business?

So i have a question here, how to build "business sense"/ "sixth sense"?? thank you in advance.
