Why don't you, cypherdoc, and whoever else be a sport and answer my theorem for a change:
"Bitcoin mining will always approach non-profitability due to unlimited supply."
What is this, econ 101?
Of course Bitcoin mining will always approach non-profitability - in a free market the production of
all products and services always approaches non-profitability. That's what markets
do.
Absent some kind of forceful outside intervention, the price of all services in an economy approaches the cost of production plus a profit margin that tends toward zero over time.
Why would you even bring this up like it's some kind of great revelation or a problem of any kind whatsoever?
