I believe that only one of 2 things will happen after the halving
A (The Most Predictable)
The price will double up to 900$ a coin and mining will resume to be as profitable as ever; things basically stay the same except with bitcoin being 900$ a coin it's the same profits for miners.
mining bitcoin was profitable so far even when price was lower than <$400 and now it is still profitable and will continue being profitable.
you don't have to worry about miners when you are not one of them.
and unless you don't have reference for what you say about profitability of mining you shouldn't make assumptions.
B (My Favorite)
Bitcoin's price consequently will crash due to massive selling once reaching a certain point of profit say 800$; this massive drop in price will cause miners to stop mining due to it no longer being profitable. Due to the lack of mining over a month or so difficulty will drop down to the tens of thousands, once again inspiring miners to mine and rebuilding the bitcoin economy back bringing a much slower steady rise to bitcoin up to a price which is okay between miners and consumers (Maybe 700-800). Just my guess; put your thoughts below!
many like you believed bitcoin will crash when it reaches $1000+ a couple of years ago when this happened. this crash took this long to take place.and this so called crash was only because there was a bubble.
and today if there is a crash the bottom will be $500 at least.
and again unless you don't have reference for what you say about profitability of mining you shouldn't make assumptions about miners and whether or not they are going to continue.
