My small bro wants to be a dropout

I have recently completed HSC now preparing for Ielts. My small bro in class 8 earns 25k from selling valorant or pubg accounts, he was a good student now he stopped studying almost. Same phrase I had been in my intermediate time also. Because as a stock, crypto trader and funny content creator I used to earn average 40k per month. Even I was trading in my hsc days also(still somehow got Gpa-5) . I was hoping to be a dropout but now I understand the value of study as it can enhance my trading career professionally. Sorry for making it too big post. How can I convince my brother not to be a dropout as he is inspired by my past talks of study and education holding no value?
