It said his investment is $200K-ish. His YouTube stuff seems insanely popular, so he invested a couple weeks of profit at most?

I have no idea of his financials but that does sound like more than a few weeks of profit. Remember he has a lot of staff to pay, the huge office/studio space and bills for that and running stuff like the LTT Store which will have expenses also. And then supporting his family on top of that.

I imagine the LTT Store is a net positive with fantastic margins.
