"Payments" would be the acquisition of coins, running a masternode, and burning Thor.Interesting, but this might mean just making payment(s) to use their source code and development services to save on in-house development costs. That has no direct effect on the value of their coins, though it would boost the value of their stock shares.
I am not sure that Vechain is willing to subvert their business model just yet. It is a "currency" in order to incentivize decentralization, if they were looking for a company to run a server farm to power the blockchain, they wouldn't have needed VEChain for that.
