Basic Accounting. Selling a Krono generates cash, but you do NOT recognize that cash as income until it is used to purchase services. It is analogous to a gift certificate - it sits in a liability account indefinitely until redeemed.

Customers can trade or sell that certificate hundreds of times between themselves, but that initial sale will NOT be recorded as income, until that Krono is used to purchase services from DPG.

However, in reality it can be assumed that the Krono can never be traded back to DPG for cash - like a gift certificate - so effectively they have the cash to do with whatever they want. It simply just never gets recorded as income on the financials until it is redeemed.
