Guys I'm looking at the pools stats and this is crazy. We have 40% more hashing power than 6-7 months ago, and yet we are expected to only find 1/2 as many blocks. That's crazy!

Coz diff increased.

First block 1-May-2017 464270 Diff = 521,974,519,553
Current blocks Diff = 4,022,059,196,165

So Diff increased ... 7.7 times since then.

So you'd expect to find, with the same hash rate, only 1/7.7 as many blocks per day compared to a year ago.

Correct me if I'm wrong, but doesn't this also mean that each one of our miners is expected to generate only 1/7.7 = 12% the amount of BTC it was expected to generate a year ago? With the diff increasing this fast it can't be much longer before the current generation of miners are no longer profitable without a serious jump in BTC value.

I remember 2 or 3 years ago people running 1TH+- miners (S5's/S4+'s,SP20's, C1's) and they only profited about $20-30 per machine , per month and it was STILL profitable to run even at high power prices. Today, an S9 still earns a minimum of +50% even if you're paying the US average of power costs.

I wouldn't recommend an S7 or below though unless you're using solar and have a huge deficit that the crappy power companies give you a laughable credit of around $0.03 on. Then those are still profitable as well.
