Make a simple calculation.
I know you are probably amazed by your current results, but keep in mind some day Internet might END, therefore IM will end.
I'm not saying this is going to happen 100% within our lives, but just like everything, it might end up shortly or a bit later.
If you graduate you will have the knowledge + title for the rest of your life.
Taking into account the society we live in, you will be treated with higher respect by having finished school + you will be able to get 9-5 job once IM dies.
If IM ends within 5 years you will have to start the school from the beggining with some kind of mental discomfort.
On your place I would focus both on school and IM.
These are 2 separate things and I wouldn't mix them up.
The fact you are making a bank at the age of 15 does not make you (in some case) better than anybody else in your age.
It means you have some kind of better understanding of the IM than others have.
Both are beneficial, but I wouldn't take advantage of one , by leaving behind the other one.
You can have both, some day school ends and you can go full time with IM.
Just my 0.02
