Does Alex get paid on his stream? if so then goodbye Alex' income.

He's rich, he'll be fine financially. He's doing it for attention

I don't think he's rich. He did said it but i think he was lying to DG. There's a chapter where he's streaming and someone sends him some currency and he says to himself "right, this is why I do it". Or something along those lines. I don't remember the exact chapter. So that's why i don't believe he's rich. I guess streaming is just a part-time job that pays really well.

He was referring to feeling a sense of belonging and validation, that he gets from his audience. In regard to money, he likely isn't independent that wealthy. His parents bought him his house, so likely doesn't have the same major living expenses like say DG. He earns money from his camming streams, and is no. 1 on the network, so he does still earn a decent amount, but it wouldn't be enough to afford his house for example.
