Seeing as players can easily just make a hole or simple structure to put their chests in, I'm not sure if it would do well.

One thing you COULD do is make a large auto farm and let people pay you to use it.

Maybe they'd have to buy a button from a chest, and then place it next to an iron door or something to enter.

In V6 there will also be a way to auction your items, so if you made an efficient method of getting items, you could make money that way too.

Personally, I have plans for making things quickly and efficiently in V6, but I won't tell you all of my secrets.
