It's so easy to get scammed or otherwise fucked in this industry. If I send that much and make so little I tend to think I'm just making someone else rich.
Generally it's something like this for me
< 1:250 = FUCK YEAH!
< 1:1000 = Worth pushing hard
1:1,001 - 1:3,000 = Maybe worth it?
> 1:3,000 = Forget it.
> 1:20,000 = Note what else they own and blacklist
