Absolutely right, But, Actually that is very difficult to do many entrepreneurs and on average they like to speculate, initially come with a good concept, pure and very maintain performance. slowly they themselves change the menu to be ordinary.
Actually the more products there are, the more choices there will be for users to choose which one is worth buying because the basic principle is liking and being interested in the products offered.
Demand and supply of products that are continuously available in the market will continue to exist as long as the product is still in demand by many people at this time. Because only two things can make each product more expensive in the market, namely because there are many enthusiasts and the other is because the supply is already quite limited while the interest of the users themselves continues to soar in the market.
Currently, entrepreneurs who have been successful and famous with the products they created previously are also still trying to create new products in order to be able to produce new money from the product in the future. So things like that cannot be denied because the competition in the market never stops as long as there are still those who make products differently with uses that are not much different.
