OP just copied and pasted text from a few years ago hoping for free merit..
sorry not original. and even if it was original. im sorry but its not rally teaching anythng
very lazy
(edit:OP now seems to have edited post to mention 12.5btc)
firstly there are 12.5 coins per block now (yea the OP's post is mega out of date as it originally said 25 coins and a price/btc of ~$228)
but more importantly. the 12.5 coins per block do not all go to exchanges to become the "supply" of exchanges to be part of the market price
