I tried searching about it on google but did not found any correct answer. So, I just wanna know. What is the legal least age for doing marketing? I mean creating websites, SEO etc. Thanks in advance. Edit: What about a 14 years old kid? Yeah, It may sound like "what" but yes. I am a 14 years old kid who have earned pretty good amount of money via CPA. Ill be starting my big project next month which may bring me thousands of dollars per month so I was wondering if there is any least for marketing. My dream is to become world's youngest millionaire. Beating "John Koon" . Country: US Territory: Fashion Net worth: $80 million Age: 16 Ashley Qualls Country: US Territory: Website Net worth: $8 million Age: 14 Tyler Dikman Country: US Territory: Technology Net worth: $3.7 million Age: 15 I would like to beat these kids and become one of the world's leading youngest self-made millionaire and world's youngest CEO. Some of problems that I think are solved: 1) Paypal account: I already got a verified paypal account that is connected to the bank account. 2) Bank account I already got a bank account, This bank allows kids to register. Do you think I may face any other problem?
