Bitcoin is the ultimate free market balancing system and will by it's inherent design mining can not be very profitable over the long run. That's why banks hate it. If price goes up mining power will follow until the excess profits are removed, if price goes down hash rate will become unprofitable and hash rate will go down. So the profit margins over the long run will be very slim. The real question is what happens when the margins are so slim that large mining farms can't attract investments, will mining pivot back to enthusiasts and those who want to acquire virgin less traceable BTC who are willing to mine at a small loss?
