Yeah, if you think that way (and there are others of us who do) then every $1 you make in the real world, you can convert that to 1 ~ 1.5 million credits here. This is openly allowed to do, you just have to learn how to trade in bitcoins and sell stars. There are also a few other ways.
(The other way around, is not allowed according to the rules. It's complex; you can read about it at various places in the HV wiki

I have built up a few good ideas for contests (not themed to holidays) but the one I'd like to do ought to be big, and I have not enough money to reward people's participation effort and time. (I may also need to have a lot of free time to organize it, which I don't at the moment, but occasionally I do)
Basically my idea is similar to our avatar beauty pageants few years back, which ran repeatedly and with multiple beauty judges (contestant entries could optionally be re-used). Except that instead of aiming for the usual hot pics, we try to find the ugliest or most poorly drawn pictures or anime screen caps that we can.
I don't mean like orc or goblin ugly, but like an amateur picture that someone drew too sloppily, that looks super funny because it is so bad and deformed.
Ideally what I'd want for winning pics is for them to be taken out of an anime, in a normal non-joking scene, where the characters look relatively normal for that panel, except that as it animates a sharp and fast eye may notice that a terrible in-between frame flew by, and if you rewind and pause on that image it looks ridiculous. Like one eye way bigger than the other, or one leg way longer, etc. Or the animation itself could be the entry, like if someone punched someone else but poorly animated and also the punch sound occurred 1 second early or late.
