The Accumulation Apex:

The phenomenon of an individual or organization surpassing the point at which their bitcoin accumulation outpaces their fiat earning potential.

I haven't seen anyone else comment on this yet.

When an individual or organization holding BTC reaches the point where their fiat gains no longer make a meaningful impact on their bitcoin stack it alters their incentives. 

For example, the incentive to support bitcoin projects and other bitcoiners takes precedence over fiat any plans. 

This is a stepping stone on the bitcoin journey and it could be the primary difference between those who are crying during upwards fiat price action and those who are cheering.
