The bitcoin price is unrelated to mining costs or coin inflation (block reward).
Wow dude, just wow.
You are insane.
Its actually realted to a large level. 3600 coins are generated from mining and can be dumped daily. If halving happens, then that dump would decrease. So in a way, price fall will slow down, and possible rise will happen.
Well how do you account for the price rising as inflation has fallen since 2009?
I'll say it again. The bitcoin price is not related to the cost of bitcoin mining.
