Is e-commerce still doing well now? why ...

It's not easy to do it now, and it's not the first time to eat crabs. Capitalists seized the opportunity, seized the lifeline of the whole e-commerce, and established completely selfish rules of the game. Any small boss who joined later only made money for capitalists in this rule.

Unless your things are original, others can't imitate them, and there is no similar model.

Or, there is a new platform with few users, low cost, high customer quality and many groups, and there is still hope to do it well.
