A user group that has not been fully explored in the Internet industry

Users are differentiated by age:
0-10 years old, baby-friendly, parent-child websites
10-20: education, games ....
20-30 years old, traveling, making friends, community, consumption .....
30-50 years old, personal financial management, political affairs, news ,.....
50-years old, no ......
Groups over 50 years old have obvious characteristics,
More free time
Strong payment capability
I hope you will discuss how to attract a large group to the Internet, or what kind of model will be used to drive a group of middle-aged and elderly netizens.
 
Although it is not difficult to say something, in the long run, the feasibility of this project is still there,
Currently, the people who enter the aging structure and those who will enter the aging population in the future have greatly improved their cultural quality and Internet awareness. Let's assume that if we become old people, do we often access the Internet? On which networks?
If we can grasp the current cognition and potential needs of the elderly on the Internet, I think this plan still has a large user market.
How to grasp the aging people's network consumption

First, it must be free.
Product operation process, user experience is simple and clear
Start with a game suitable for the elderly (data shows that many elderly people are also interested in online games)
Develop into an elderly community
Further development can include discounts for low-end and middle-end consumer goods, elderly product malls, funds, stocks, debts, etc.
