# The wisdom of charge

### 1. let rich people pay.

In one respect, rich people got money for you. In another respect, you are helping poors.

### 2. charge less-important feature

You'll get many users. Most of them love your service because they can use your product for free. A few of them have higher demands, you satisfy them if they pay you money.

### 3. charge commercial use

If they can make money by using your product, they should pay you back in return.

> They normally won't say no, because they rely on you to make money.

### 4. add uniqueness to your product

If you can't find similar products in the market, it means you are the one who set the price. You can set whatever you want, as higher as possible. Since they really don't know how much money you cost for making that product.
