Perhaps new (fresh accounts) - in particular ones transacting with dApps such as Steem Monsters, dtube, VIMM, etc get a pooled bonus to enjoy those apps... sensibly (ie accounts with x steem power, zero flags, and transactions of a certain json) get discounted "transactions" in terms of resource credits that tapers away as their account grows. 

Surely every account at dolphin / orca / whale status isn't expected to use their entire allocation of Resource Credits in a single day? Does this not create equilibrium? I could never imagine using my entire bandwidth allocation pre HF20. 

I may be missing the whole point, but the true cost of not-transacting on chain at all for these new and on boarding accounts is far greater than the "true cost" of a transaction in terms of blockchain computational cost. 

I know that this update lays the foundation for SMTs, and I might be missing something about how RC interact with this, but please, think of the minnows! 

They're our future!
