The whole slot YouTube thing as a business is weird to me, because it's something where you're knowingly sitting down to lose money in order to (possibly) get views.

I suppose if you're playing either way, it's fine, but as a business model it seems off. Compare this to the poker streamers, who get money from their streaming efforts, but also are playing in a game where they believe themselves to be +EV.

If your channel is big enough, I guess you can overcome that via YouTube payments, but that has to be a frustrating expense to deal with.
