Sell one's technology
Sell your own technology, what source code is in it, what functions to sell, go to some platforms to receive some outsourcing orders, and so on. This kind is customer-dependent, which means you have customers first, and then you have money. But many people will die on the floor without customers.
Use your own technology
Using your own technology, you don't need to ask anyone for help, do data analysis, invest some money yourself, such as speculating in stocks and futures, control how much you earn and how much you lose, and don't have to deal with others. This kind of self-reliance does not depend on others, but directly on technological advantages.
Data analysis to make money
By collecting data from the market, storing it in the database, and then finding the most suitable entry point according to certain analysis rules, small funds can enter and earn a takeaway money a day. Of course, if you want to make more profits, you should control yourself and take your own risks. You don't need to ask anyone for help, and you don't need to deal with any customers.
