TOPIC: [Dark RP] Tf2 like trading

What would you like to add?

A new trading system for ascetic items
Players would be able to buy a crate for around 1-5 mill, upon opening they would receive either an exclusive hat/pointshop item or ts-icon. Players would then be able to trade said items freely for in game cash and other similar items with other players. A new economy would most likely then procure from the trades.

How would it benefit the server/why do you want this to be added?:

A more solid economy would get added, players would also have a new money sink.

Could this be exploited in anyway, and if, how could we make it non-exploitable?

Some players currently have enough money to buy enough "crates" until they get one of each item that could be implemented. Could be good could be bad?

I think this a very good thing to have but i dont think people would trade that much but it would be cool to have
