Are you reaching out to any sponsors?

I did sponsor placements for over 80 companies (mostly gaming) from 2009 to mid 2020 (I mistakenly focused too hard on live events, cost me my side business). I placed a ton of sponsors with content creators that reached out first.

There are paying sponsors available, just no one contacts them and they have no idea how to go about contacting content creators.

Also, do you have a form of contact in your bio? If not due to concerns over spam, make a new e-mail and only use it there. Most sponsors are not going to take the time to search more than your bio for contact information. They simply don't have time.

You don't have to be a big fish to get big sponsors. You just have to make it easy for them to sponsor you.

As far as making money playing games, there are TONS of paying apps (most are aggregates - play X amount of time for Y currency). Trade out for like $5+ gift cards to Target, Walmart, Visa, etc.

Hopefully your experiment goes well here. I knew of this particular game but was not aware it paid.
