Am I crazy for doing business even in a death game?

I was absorbed in being a street vendor in a certain online game when one day I suddenly got caught up in a death game…… ……But up to this point, it's just a common, ordinary template found anywhere. To make matters worse, I'm an introvert, socially awkward, and a shut-in. The only thing I can do is make money (and even that, just small change at best……) "Huh? Death game? What's that? Sounds delicious?" I've never even joined a guild in the online game, so there's no way I could do that. The only thing I'm interested in is making money. This is a story of how such a chicken-hearted guy like me survives a death game through money-making.
