Monkey Trading Hub

The monkey trading hub is unlocked at rank 10 and is found on the home screen. This is the place where you can use monkey money that you have earned. When you enter, you will see three options. You can view your inventory, go to the monkey king's shop, or check out the player shops.

When you view your inventory, you will see your special agents, monkeys (in-game free monkeys), and supply crates (which are classified as special agents and will give you a certain amount of lives or cash).

In the monkey king's shop, which is where you can buy special agents, monkeys, supply crates (cost increases the more lives/cash are rewarded), and other items with monkey money. Here, you must wait 12 hours before purchasing another of the same item (i.e. you must wait 12 hours after purchasing a mortar to purchase another mortar, but you can still buy a bomb tower during that time).

The player shops are the best part of the Monkey Trading Hub, but it is only available with an internet connection. Here, you can buy and sell agents, monkeys, supply crates, from other players. For people that might not already understand this, when you buy something from the player shops, the money will go to the player that sold it. When entering the player shops, the sales that have most recently been put up on the market will be show as default, but you can also search for items. You can search as for a category or specific item and set a price range. When you do search, you can choose to display recent or cheapest. There is also an option to sell an item. When you select this option, your inventory will open. Then, you select which item you would like to sell and that quantity. Then, you select he price of the item. You can set the cost to definite, where any player can buy it for a certain amount, or auction, where you set either the total amount of time the auction lasts or the amount of time between bids before the auction ends. Whoever has the highest bid at the end of the auction wins.

The idea of purchasing items like this has never been included in a BTD game, except partially in BMC. For a game series this big, there should be some king of shop like this.
