As weird as it sounds, the chaotic race of Demons does have their own currency beyond just mindless loot and slaves. Often referred to as Pitcoins, these small golden disks tend to be one of the most fluctuating forms of payment found all over the Cosmic Hourglass. Sometimes they're able to buy entire patches of lands, other times they are worthless as a form of payment.

History

After the Tri-Realm War, the Aspect of Greed came together with Devils to try and unite the Infernal Realm through a way only he knew: Bribery. By creating a currency under his name, the pit lord forged for each Demon on the Infernal Realm a coin, which would be distributed over time. Through the means of a binding, each coin would force the Demons into submission, making them servants of the Aspect. With such an army, he could end up conquering the upper planes with ease.

Then, the unthinkable happened: While he was able to take over a large assortment of the plane, some denied his control or lost their coins on other realms. Those few Demons caused a domino effect that broke down the binding of other fiends, completely neutralising the control across the realm.

As the coins' bindings were broken, their value began shifting with the fluctuating Demon population, resulting in their worth both skyrocketing and plummeting constantly. Greed, knowing the failure of his project, decided to put it all under a guise and made his servants start a cleaning operation. Over the course of millennia, their kind traversed the multiverse in search for said coins, through all means bringing them back to the Devil's vault.

In the Infernal Realm

Here's a deal: you give me that Coin and I'll give you something of equal value in return. If not, I'll have to just pry it out of your torn-off hands. — Greed Demon Merchant

Amongst the layers of Hell, Pit Coins tend to not have any particular value in terms of an actual currency. Because of the fact that most Demons have their own abstract forms of payment, things like emotion, they find physical money unappealing to use. Most often just trade their goods or pillage settlements for it.

However, Pit Coins aren't worthless, as some Demons will actively trade them depending on the value you hold for it. What the currency lacks in economical value they often make up to in emotional, embedded with enough chaotic energy to last them quite a while. The more relished one Pit Coin becomes, the more it becomes worth for a Demon, giving greater and greater services for older ones.

The Aspect of Greed, However, is known to pay top-notch to get his coins back in the vault beneath the Field of opportunity. Using his servants to comb the multiverse, they collect every coin both lost and found to bring back to their master, offering other artefacts in return. And if that doesn't work, they just use force to rip it out of the hands of any mortal foolish enough to deny them.

On Fabulae

You know why we have the term "Being in a pit" for merchants? Because of these bloody things. — Merchant

Merchants paid in a Pit Coin consider it one of the most unlucky things to sell goods for, as its fluctuating financial value can cripple their business. Not only do these Coins tend to have no constant towards the base gold price, it seems to corrupt the surrounding value of other coins and objects: items change from their quality and coin bags fill or empty if one Pit Coin is present.

However, amongst demonic cults and devil worshippers, these artefacts are commonly used to bribe and pay higher demons. Binding said fiends to the Coins again, they are forced to obey their summoners until the deed is done, incapable of refusing. However, while Demons do give their services and knowledge for the payment, most will try finding a loophole that benefits themselves greater than their payer. Anything from poorly chosen words to untold rules Demons will exploit, having many cultists be warned with what they wish for.
