A monk read my palm and said that I would be rich or expensive in the future. I gave him money, but he didn't accept it. What is accuracy?

True Buddhist disciples don't read fortune-telling. You just need to ask a regular temple. Now many monasteries can ask for visas. To put it bluntly, it is to meet the needs of all beings and is convenient. If you are still skeptical, I suggest you go and see the Real Buddhism edited by the feast master, which will have a detailed explanation.
