Sure, the past 8 months has seen a huge surge in price, but if you look at the difficulty, that has surged almost right along with it.  

I think you're right in that the recent surge in price has increased profits for miners, but not to the extreme that you make out. I think the recent spike in profit is going to drop back down to normal levels with these new S9's being released in the coming months. That's where our opinions differ. I think it's going to be to where the S9 is no longer going to be extremely profitable, just back down to where profits were before, which was normally profitable to start with. It's not like mining wasn't profitable 8 months ago before the price of bitcoin surged 1000%. I've been turning a profit mining for years, only recently has it become stupidly profitable, and of course we're all expecting that to go away. What we're not expecting is your prediction that our miners will be making nothing in a couple of months.
