Hmm,
After the ULI,
To actually benefit from a price increase the holder has to sell his coins and this costs him future staking ability to earn transaction fees.
Anyone can buy ZEIT and they decide how much or how little profit they make.
I suggest you study BTC inflation model, where a declining inflation rate promotes a increase in price over time.
Then you will understand why the ULI is so important.
But back to your original question , why would someone buy ZEIT after the ULI.
To Wait for and sell when the price increase
or
To use as a way to transfer value from one entity to another
or
To own enough ZEIT to be able to stake and earn transaction fees ,
and live off of selling nothing but their transaction fees.
*** With the Switch to ULI Completes,
ZEIT becomes similar to an ASIC it runs and safeguards the network
and provides a livelihood for its owners.
It has none of the failures of the PoW ASICS,
ZEIT is Energy Efficient and will not require new equipment be purchased and cooling a warehouse to run. Plus it already has 20X BTC current onchain transaction capacity.
ZEIT is the Game Changer and time will prove it to all,
you can recognize it now and profit later , or ignore it.
Your Choice.
