would have to say the last 4 months have been stable price wise and difficulty wise.
from jan 20 to may 25th price has been 228 to 238 with a peak near 298
and diff was 43.9 Bill on jan 20th it is now 48.8 Bill
Pretty smooth for 4 months.
I wonder what the next 4 months will bring?
I'm thinking we will see new gear sometime within it. But I could be very wrong on that. New gear/chips has slowed down to a crawl with low btc to blame in my opinion. I think the companies broke the cycle of new gear and are enjoying using the old gear for a little extra and slow the R/D down a little (although some could have chips or something up there sleeve, waiting for right moment to launch).
I just don't see near the hardware expansion it seemed like we were always doing. And eventually halving will come into effect and could be scaring some off. I'm unsure how halving will be done with existing miners.
There needs to be either a significant hardware improvement (< 0.25W) before the halving or there will be a huge diff drop and/or price rise. As it stands now most hardware including the S5 would become unprofitable overnight.
