Develop an altcoin and promote it in a specific country or region. Do you think it will be profitable?

For example, in China, China has many consumer users and huge investment potential.
Do you think this can be done? How much money will be needed and how long will it take?
Please come up with your ideas, I'm preparing to do this
I would like to ask everyone to provide me with ideas

Dear seniors:
I am a non-technical person, I am from China and I would like to know how much does it cost to develop a cryptocurrency like Bitcoin?
need:
1. Website to introduce detailed information about this cryptocurrency.
2. Blockchain browser
3. A desktop wallet (preferably one that can mine directly using the wallet and computer. There are many high-quality users in China who are not technical and want to participate in such a project, but they do not know how to build a mining pool and do not know how to mine. mine)
4. White paper
I want to develop such a cryptocurrency and bring it to China to promote it so that more people can participate. After all, many Chinese people have missed the opportunity to buy Bitcoin at low prices or mine Bitcoin for free.
In China, there are very few opportunities to participate in cryptocurrency private sales. Most people can only buy them on exchanges. If there is a cryptocurrency that can be mined for free, I believe it will be popular.
In China, 99% of users do not believe in projects made by Chinese people, and there are too many cases of being defrauded by their own people.
As long as it is a project run by non-Chinese people, it has high credibility and the enthusiasm of users to participate is also very high.
I have some money, but not much, and some investment ability. I also hope to bring it to China to make money.
I hope all seniors can give me some advice, thank you very much.
I also hope I have a technical partner if the project is successful.
I don’t know if I can put my email address. If I can, please let me know. I will actively communicate with you and work with you. I can solve the money issue.
I don't speak English. I use translation software. If there are any mistakes, I hope you can forgive me.
