Buddhist disciples do charity and support their families with the proceeds from stock trading and futures. What is the reward?
As long as it is a socially recognized way to make money, it can be called legitimate business, so it is no evil to use profit to do charity and support the family! But according to the view of pure Buddhism, there will be greed and ignorance in any business, which is the accumulation and realization of desire! Choose to see how you understand it. I hope you can see from this that Buddhism is not secular. Can you understand?
