You put tradekey.com as a competitor to Alibaba. Have you ever tried it? Do you know anything about this company? You need to do in-depth research before recommending companies. Tradekey is a big scam, that sells the hope of getting customers, which you will never get through them. They create profiles of fake companies, and connect verified and well established companies to well known scammers. I will even say that Tradekey might actually hire those scammers to take people on rides for months.
Plus Tradekey will never give you a good sense on where trends are heading, or allow you to identify that next hot product that'll allow you to make sales online.
I suggest you revisit the whole article, and research the industry in a serious manner.
