How should one alter expectations of the future number of BTC mined on any rig available today in the scenarios that 1) BTC price rises a lot, say 5x to $4000 in the next few months) BTC price falls a lot (say 75% back to $200), or 3) BTC price remains stable at the current price around $830. Is there a predictable impact of such price movements on the ability to mine BTC?

Thanks if you can help.
