Bitcoin is 89% premine to any kid born today.
In 2140 it is 100% premine to any kid born that year.
Why the future generations don`t get any rewards?
What kind of design is this satoshi? to enslave the future of humanity?
The question is, would those future kids minding to mine on that time? When it comes to rewards then they would really be still making via fees when pushing up transactions.
Presuming that bitcoin did able to survive till 2140 which indicates that it is already globally adopted in full scale which means transactions in the network would really be more than on what we are
seeing at the current.
Also satoshi didnt really create nor make bitcoin about enslaving yet he didnt even expect for his creation to make this big as of this moment.
