I noticed in my account worth that one of my most expensive items is a Magical Dark Matter Duct Tape - 42mil o.o
I searched the shops and sure enough they are priced around that - I don't remember it ever being that expensive though, so was wondering if it's just crazy inflation :/
It probably did inflate like mad, I've got items like that that I bough cheap as crap and are now worth a small mint
The prices on the account worth fluctuate daily, depending on what people have paid for that specific item that day. If someone uses a really cheap item for art payment (50mil, for example), it shows up at that said ridiculous price and knocks your account worth up a few mil.
