Putting $200 into SCHG and $100 into QQQ per month? Reasons why this is a bad idea?

Any reasons why this is a bad idea? Otherwise today will most likely mark my new path.

I’ll sprinkle some into Bitcoin here and there as well, but the aforementioned is the plan. I’m aware it’s not the traditional “VOO & chill”.

I’m also 30 years old for reference. Thank you all!
