Yes, ofcourse parents are worried about what their children are doing and in what way they ars earning money.
According to me people who are well educated and have experience would never say no to Make Money Online and Bitcoin. Infact my parents encourage me to make money from bitcoin because its a good opportunity to earn money when you are still completing your education. People who are not aware of Make Money online and are less educated in that case children’s should make them understand, show them proof and logic and risk vs reward in number
