The e-commerce industry is one of the fast growing markets, and every year the turnover of e-commerce grows. Emarketchain wants to solve some problems existing in this market, removing intermediaries in this market, manufacturers can directly sell their goods to consumers, while the price of goods is reduced which is very beneficial for consumers.
That's why Amazon is also one of the fastest growing companies. It feels like they are just a synonym for the whole e-commerce market by now. If they launch their own crypto it's going to be interesting.
